- I have found that the MK_LIBRARY_HELP.PRO procedure supplied in the V3.0.0
- User Library does not work under VMS IDL. (This procedures allows users
- to create their own .HELP files.) The created .HELP file has
- incorrect byte offets associated with each procedure name, so that one does
- not always get the help that one asked for. The problem is caused by
- the additional control characters introduced by VMS.
-
- I have a fixed version of MK_LIBRARY_HELP which I will send to anyone who wants
- it, but I'm not sure it is the "best" way to fix it. The two changes I made
- were
-
- (1) The temporary file USERLIB.TXT is opened (on the unit txt_file) with
- the /STREAM keyword
-
- (2) Since the EOF command does not work with /STREAM files, I use the
- On_IOerror command instead of EOF to flag the end of file.
