I'm posting a revision of my DCL_MENU SMG/FORTRAN based menu command to
VMSNET.SOURCES. I can't promise to fix bugs/add enhancements, but I'd
appreciate comments on the usefulness or otherwise of the progs and will
endeavour to respond with fixes/enhancements.
Abstract
========
RUN_MENU[/qualifiers] [filename]
Displays a scrolling menu on the screen and allows the user to select from it
by moving the cursor and pressing <Return>.
The cursor may be moved by :-
- pressing the arrow keys
or - entering the first letters (first match is taken) of a choice and
pressing <Return>, or <Help> or <PF2> or any arrow key
Pressing <Help> or PF2 displays help text on the current item.
When an item has been selected :-
a) its number can be returned to a DCL symbol
and/or b) the item text can be returned to a DCL symbol
and/or c) an associated 'action term' can be returned
to a DCL symbol
in addition either
a) an associated 'action term' can be executed in a subprocess as a DCL
command (after which the menu is redisplayed)
or b) an associate 'action term' can be executed as a DCL command (the
menu is not redisplayed)
Changes Since Previous Version
==============================
-Menu entries may indirect to another file (which may indirect ...)
-Menu entries may be translations of logical names and/or symbols
These changes allow a single menu file to present different options according
to the values/presence of files/logical names/symbols
-The display of filenames from the /FILES qualifier has been improved to
suppress display of constant portions of the filespec. This default behaviour
can be overridden by added qualifiers.
-A 'Block' mode display has been added (=matrix in which each element takes the
same space).
-The .CLD command definition is compiled to a .OBJ file and linked with the
Fortran, so that the command doesn't need to be added to the DCL command
tables.
-We've changed the DCL command from MENU (which users, reasonably, expected to
actually display a menu) to RUN_MENU.
