_The EDX text editor_
EDX is a powerful EDT-style TPU based text editor which supports
all the major functions of the EDT editor plus many other
advanced features not available in the EDT editor or the newer
EVE editor. It is intended for users familiar with the EDT
editor who would like to switch to a faster, more powerful
editor without having to learn a new editor all over again. EDX
also supports a WPS-style keypad mode for users who prefer the
WPS-style keypad.
Following are some of the advanced features of the EDX editor
which are not available in EDT or EVE:
* Built in spelling checker with 90,000 word dictionary. Spell
check a buffer, range, word, or display the dictionary and
browse. Includes guessing algorithms and personal
supplemental dictionary support.
* Edit modules within VMS text libraries. (Fixed).
* Obtain a directory listing
Include optional /SIZE and /DATE qualifiers.
Read in a selected file from the directory listing,
delete a selected file, or lock a selected file.
* Wildcard search and replace mode, with optional string to
exclude as a match, case sensitive or insensitive.
* List all lines containing a specified string or wildcard
pattern along with the corresponding line number.
(The EDT 'TYPE ALL' command)
* Search for and highlight matching parenthesis.
* Lock files, preventing others from editing them while you do.
* Sort a buffer, range, or columnar range.
* Columnar cut and paste in insert or overstrike mode.
* Translate a buffer from EBCDIC to ASCII, and vice versa.
* Compare two buffers line by line.
* Translate DCL symbols and logical names.
* Create DCL symbols and logical names.
Note that all of the above features are performed within the
editor without spawning a subprocess.
EDX is built on the VAX Text Processing Utility (VAXTPU). Users
familiar with VAXTPU can dynamically extend the editor's
abilities by adding new functions which perform complex tasks.
EDX makes this job easier by defining over 50 general purpose
functions not available in VAXTPU itself.

random_numbers.doc
A paper on computer random number generators, with analysis of
several commonly found random number generators including
MTH$RANDOM (used by VAX FORTRAN and BASIC) and the standard ANSI
C rand() function. Anyone using random number generators will
find the research done here most interesting and enlightening.
Also contains a number of paradoxes in probability to thoroughly
amuse and confuse you.
random_numbers_test.for
Code for performing the chi-square and KS tests on a sequence
of 'random' numbers to see if they appear random or not.
-----------------------------------------------------------------------
pentium_bug.doc
Explains the pentium floating point division bug. Describes the
Radix-4 SRT division algorithm. Analyses which numbers the old
Pentium will divide incorrectly. (Unfished, send inquiry to
deleyd@netcom.com)
-----------------------------------------------------------------------
minfunc.zip (OS independent. Code should be easily transportable
to other systems.)
Given a scalar function F, which is a function of several scalar
variables {x(1),x(2),...,x(n)}, find the values of
{x(1),x(2),...,x(n)} which MINIMIZES (or maximizes) the value of
function F. File OPTI2.FOR provides a choice of the Conjugate
Direction Method of Fletcher and Reeves (CDM), or POWELL's method.
------------------------------------------------------------------------
prime_numbers (OS independent. Code should be easily transportable
to other systems.)
Routines for generating prime numbers and for finding the prime
factors of a given number:
factor.c - Routine for finding the prime factors of a
given number.
nextprime.c - Function to round a number up to the next
prime. See file NEXTPRIME.DOC for further
details.
makeprimes.c - Routine which generates all primes up to a
specified number of primes. This uses a
modified version of NEXTPRIME.FOR to generate
all primes up to a given number of primes and
print them out. Change parameter NUMPRIMES to
the number of primes you wish to generate.
========================================================================
VMS SPECIFIC
autologin.zip (VAX/VMS. Concept has not been tested
on AXP/OpenVMS systems)
An example program which causes a terminal to be logged in
automatically as if a user had entered their username and
password at the terminal. The terminal "jumps to life" by
itself.
------------------------------------------------------------------------
bookreader.zip (VAX/VMS & AXP/OpenVMS)
BOOKREADER_TO_ASCII reads a BOOKREADER file (such as one of
the *.DECW$BOOK files on the VMS documentation CDs) and
extracts the text, tables, and examples into an ASCII text
file. [Designed and coded by Claude Barbe - Schlumberger -
SDR Ridgefield, CT, USA 12-Jan-1990 (barbe@sdr.slb.com)
(Internet).]
------------------------------------------------------------------------
calc2.zip (VAX/VMS & AXP/OpenVMS)
CALC2 is an emulation of a Hewlett-Packard reverse polish
calculator for video terminals.
------------------------------------------------------------------------
force_deallocate.zip (VAX/VMS only. There are substantial
differences in how this would need
to be coded for AXP/OpenVMS)
An example program which queues an AST to a target process
causing the target process to deallocate a device it has
allocated. Requires CHMDKRNL
------------------------------------------------------------------------
miscdoc.zip
_Micellaneous Documentation_
Miscellaneous possibly useful documentation:
ANALYZE_CRASH.DOC
An example analysis of a VAX/VMS system crash using the
Symbolic Dump Analyzer (SDA).
ANALYZE_PROCESS.DOC
An example of how to analyze any process on a running system
using the Symbolic Dump Analyzer.
DCL_TO_SYS.DOC
It is not always necessary to spawn a subprocess to execute
a DCL command from within a program. Often the same result
can be achieved much more quickly by using the appropriate
system service routines. DCL_TO_SYS.DOC matches DCL
commands with the equivalent VMS operating system provided
routines.
FORTRAN_ARRAY_ADDRESSING.DOC
The correct way to traverse multi-dimensional arrays in FORTRAN.
ITEMLIST.DOC
Explanation of using itemlists in system service calls.
MODEM_INTERFACE.DOC
Useful information on interfacing modems to VAX computer ports.
PAGE_FAULTS_AND_ARRAY_ADDRESSING.DOC
Understanding what a page fault is can sometimes be crucial
to writing efficient code. An overview of virtual memory,
page faults, and array addressing in code is presented.
XMODEM_CRC.DOC
Article describing how Cyclic Redundancy Codes work.
_And Miscellaneous Programs_
chkexpr (VAX/VMS & AXP/OpenVMS)
CHKEXPR is a program which will warn a user if his account is
about to expire. If a user's account is about to expire, the
program will print a warning message, otherwise the program prints
nothing. If included as a part of the system wide login
procedure, this program will warn a user that his account is about
to expire the same way VMS warns a user if his password is about
to expire.
clrscreen (VAX/VMS & AXP/OpenVMS)
CLRSCREEN.FOR is a simple example of using the VAX screen
management services to obtain an escape sequence which when sent
to the terminal will perform a certain desired function.
big_batch_job.com (VAX/VMS & AXP/OpenVMS)
control.com
convert.com
This is an example .COM file of how to get a batch job which may
take more than a day to complete to run at night and suspend
itself during the day.
disktotal.com (VAX/VMS & AXP/OpenVMS)
Handy when a disk gets full. Makes a list of all the directories
and the total number of files in each directory. Scan the list
with an editor and find the offensive directories which have
humongous blocks. Helps you quickly find where all the blocks
have gone. Run it and give it the name of the disk.
finddir.com (VAX/VMS & AXP/OpenVMS)
Handy when you don't know which disk somebody's directory is on.
Give it the top level directory name and it searches all the disks
and tells you which ones the directory exists on and what files
are in that directory.
fragment.for (VAX/VMS & AXP/OpenVMS)
defrag.for
FRAGMENT and DEFRAG are programs which assist in transferring very
large files over flaky telephone lines. The idea is to create a
backup save set of the files you want to transfer, run FRAGMENT to
break the big backup save set file into many little files,
transfer all the little files using kermit set to FILE TYPE FIXED
with a wildcard filename, run DEFRAG to reconstruct the backup
save set file from all the little files, and recover all the files
you wanted to transfer from the backup save set. This way if the
phone line flakes out during one of the file transfers, you
haven't lost everything you've achieved up to that point.
setprocname.for (VAX/VMS & AXP/OpenVMS)
SETPROCNAME is an executable image that will set your process to a
specified name, and make the name unique by appending a 2 or 3
etc. as needed. You may also specify what character (or
characters) you want between the name you specify and the number
2,3, or whatever.
smgvt220fix.doc (VAX/VMS & AXP/OpenVMS)
This explains how to get around the "}z" glitches which sometimes
show up on non-DIGITAL brand VT200 terminals. True DIGITAL VT200
terminals accept a few extra escape sequences which show up as
"}z" glitches on other VT200 terminals. The fix is to tell SMG
that we're a VT100. If we're a VT200 terminal we switch to a
VT100 terminal, initialize SMG, and switch back to a VT200
terminal. This switch is sandwiched around the call to
SMG$CREATE_VIRTUAL_KEYBOARD (for technical reasons.) An example
is illustrated in file smgvt220fix.c
------------------------------------------------------------------------
rmsdoc.zip
_RMS file organizations_
Explanation of all the RMS internal file organizations
and how files are stored on disks.
------------------------------------------------------------------------
srchque.zip (VAX/VMS & AXP/OpenVMS)
SRCHQUE is a program which searches a specified batch queue for
a specified job name. If it finds the job in the specified
queue it returns with a status of success. If it does not find
the job in the specified queue it returns with a warning status.
This program is handy if you wish to submit a job only if the
job does not already exist in the queue. Jobs retained in the
queue on error are not counted.
------------------------------------------------------------------------
swing.zip (VAX/VMS & AXP/OpenVMS)
SWING is an interactive directory tree editor. It displays the
current directory structure on the screen and allows the user to
SET DEFAULT graphically by traveling through the tree. SWING
can add, rename and move directory trees and it can delete
directory trees (visually doing what the DELTREE type command
procedures do). SWING also creates hardcopy listings of a
directory structure.
------------------------------------------------------------------------
tail.zip (VAX/VMS & AXP/OpenVMS)
TAIL dumps the last few lines of a file.
It does NOT read the entire file so it is VERY fast.
Example:
Tail/Last=30 filename
will display the last 30 lines of "filename".
[Original author: Peter A. Portante. Modified to include
support for VFC, Fixed, and Stream record formats. All record
formats except 'Undefined' are now supported.]
------------------------------------------------------------------------
terminator.zip (VAX/VMS & AXP/OpenVMS)
TERMINATOR is "Yet Another Idle Terminal Killer" program.
The only difference is this one is ours. Read the AAAREADME.DOC
file for more information.
------------------------------------------------------------------------
usage_monitor.zip (VAX/VMS & AXP/OpenVMS)
Plots a histogram of CPU utilization and compute queue
length throughout the day. This gives a general idea of
how heavily utilized the computer is and when peek
usage times are. Takes as input the record file
generated by the VMS MONITOR utility. A similar program
plots a histogram of disk I/O queue length throughout
the day. This can help determine if disk I/O
bottlenecks are occurring and when.
------------------------------------------------------------------------
zeroacc.zip (VAX/VMS only. There are substantial
differences in how this would need
to be coded for AXP/OpenVMS)
We like to give our users a substantial discount for using the
computers during non prime time hours. Unfortunately the VMS
accounting facility does not provide a convenient way of doing
this. It only records the time a user logged in and what his
total usage was. It doesn't say what his usage was during a
particular rate period.
If a user logged in during one rate period, and then stayed
logged in after the rates changed, we had no way of determining
how much usage the user had acquired up to that point. What we
needed was a way to effectively logout a user when the rates
changed and log him back in again under the new rates, and thus
was born this program.
ZEROACC writes an accounting record for each process on the
system and resets the accounting data fields of each process
back to zero. From an accounting viewpoint it appears as if the
user logged out and then logged back in again. The user himself
is left undisturbed unaware that anything has happened. Any
program he was running at the time continues to run.
========================================================================
The following programs are available upon special request.
Send request to deleyd@netcom.com
BANNER
BANNER is a security banner and page marking program. It creates
leading and trailing flag pages as well as top and bottom page
marks for security marking your line printer output. If you are
tired of hand stamping documents - this is the answer. BANNER is
a complete tool with a command language definition, help file and
manual. [VAX86C]
EXCEPTION_INTERCEPTOR
Allows programs written in ADA to handle exceptions as they are
intended to be handled under VMS using the VMS Condition Handling
Facility. Exceptions are part of the ADA language, but ADA does
not have nearly the power of VMS's Condition Handling Facility.
[VAX90B1]
GREP (VAX/VMS & AXP/OpenVMS)
This is a VMS version of the UNIX GREP tool. It has been written
to behave just like the SEARCH command - output, qualifiers and
parameters are similar - but is able to search for patterns. It
is a complete tool and has a command language definition and
online help. It is a nice addition to VMS.
HYPHENATION
This is subroutine Hyphenate, an implementation of the TeX82
hyphenation algorithm. Sources and objects are given. [VAX88B2]
MODOBJ
MODOBJ is a program which modifies object files (modules).
Reasons for wanting to modify object files, the exact
modifications performed, and usage instructions can all be found
in the source file MODOBJ.C. [VAX87C]
TIMER
TIMER.MAR accurately times machine instructions on a VAX 11/780 or
equivalent architecture. Instructions can be found in the source.
[VAX87C]
WEAVE
Weave is a program for reorganizing and duplicating text within
files. It was inspired by WEB, a Pascal-based language designed
by Knuth. [VAX88B2]
