  An alternative, which requires only OS/2, is the REXX versions of
Stephen's BATch file.  It is not as terse as Larry's alternative, but
then, I don't have to add 4OS2 to my system.  Of course, \os2\e doesn't
have the ability for accepting more than one file at a time, so I am
unsure just what Stephen's batch file was meant to do (nor Larry's 4OS2
command) with the extra parameters.  Here is the 3 line REXX CMD file:

/* Just to let the command interpretor know that this file is REXX */
parse arg file
"start \os2\e" file

Of course, I could enhance this to say, invoke "e" for most files, "epm"
for all my .C, .CPP, .H, and .DEF files, and "WordPerfect" for all my
.DOC files....

/* Just to let the command interpretor know that this file is REXX */
parse arg line
e_line = ""
epm_line = ""
wp_line = ""
do i = 1 to words(line)
  full_file_name = word(line,i)
/* you may want to parse the name from backwards from the end for HPFS
   names such as long_name.with.multiple.periods.doc  - this file will
   not be correctly handled with the code below.  It is left as an
   exercise to the reader ;) */
  parse filespec("file",full_file_name) . '.' ext
  select
    when ext = 'DOC' then wp_line = wp_line full_file_name
    when ext = 'C' | ext = 'CPP' | ext = 'H' | ext = 'DEF'
       then epm_line epm_line full_file_name
    otherwise e_line = e_line full_file_name
  end
end
/* I don't know if WordPerfect will handle more than one file as args,
   but I will assume that it will */
if wp_line <> "" then "@start D:\WP\WP.EXE" wp_line
/* EPM does handle multiple file arguments. */
if epm_line <> "" then "@start C:\OS2\APPS\EPM.EXE" epm_line
/* e.exe does not appear to accept more than one file, but for illustrat-
   ion purposes -  you could put this in the loop above, one start for
   every file found */
if e_line <> "" then "@start C:\OS2\E.EXE" e_line
