1 SPELL
 SPELL  is  a  proofreader  which  makes  use of  a default 90,000  word
 dictionary  and  optionally  a personal dictionary.  SPELL asks  for  a 
 file  name  that  you  wish to have checked.  When a word is found that
 is not in any of the dictionaries, you will be asked if:

 o  the word is incorrect and you want to correct it in your file.
 o  you wish SPELL to try guessing what the word is.
 o  you wish to have the word  inserted into a personal dictionary which
    will reside in your sys$login directory.
 o  you wish the program to ignore your spelling.
 
 Format:

  SPELL filename
2 Parameters
 If  no  qualifiers are present on the SPELL command, then the parameter
 is the name of a file to check.  If the  /CHECK qualifier is used, then
 the parameter should be the word you are trying to check.  If any other
 qualifiers are used, SPELL ignores all parameters.

 The  file  specified  will be rewritten  with any changes that you have
 requested during the SPELL session.  No extension needs to be specified
 if the file has one of the default extensions .RNO, .TEX, .MSS or .TXT.
 The appropriate syntax  will  be  used  for  checking  files with these
 extensions so that  embedded  commands  do  not  register  as incorrect
 spellings.  For this reason,  it  is  important that you should use the
 correct extension on any files which you are going to check.

2 Personal_Dictionary
 PERSDICT.DAT  is the personal dictionary file you create through SPELL.
 It uses a tree-structure for its organization.  As  a  result, the file
 cannot be  edited or altered  through normal means.  List this file and 
 delete erroneous words by using the SPELL/PERSONAL command. Editing the
 file will destroy its structure and you will have to delete it!
2 Qualifiers
/CHECK
 The  CHECK  option  allows you to check if a word is in one of the main
 dictionaries used  by  the spell program.  You specify a command of the
 form:
 
 $ spell/check word

 to check if "word" is in the dictionary.
/PERSONAL
 The  PERSONAL  option  is  used  to  maintain your personal dictionary.
 Since  this  is an indexed file,  you should never try editing it using
 EDT or any other text editor.  Instead,  this  SPELL  option allows you
 to list and optionally delete any words from your personal directory.

 Within this mode,  the List option operates circularly.  After you have
 seen all the words in your personal dictionary,  you will be taken back
 to the beginning  and  successive  List commands will display the whole
 dictionary again.
/LOGGING
 You can select this qualifier in addition to a file name if you want to
 produce a list of the changes made during a run, in a file with an .ERR
 extension.  This  qualifier  is  ignored  if  any  other qualifiers are 
 present.
