In the Purdue doc files, the changes for vms are detailed below in
Appendix 1.



CAUTION
-------

Optional parameters are case sensitive.  The VMS C Run Time Library will
lowercase all parameters UNLESS they are in quotes.

Ex: If you want to send -NFred to a program:

-NFred will arrive as -nfred, so use "-NFred" instead.....

Appendix 1 - Changes in VMS programs that are not documented in the Purdue
doc. set.

VMS Symbols Needed:

File Names
----------

RCS commands only accept the source code file names, rather than the
working file name.  The work file name is constructed using the 
RCS_REFERENCE_DIRECTORY symbol.

RCSCLEAN.EXE only does one file at a time.  No wildcards are supported,
but they are coming soon.  Hook it to a COM file that uses f$search() to
get all files matching a wildcard.

Work File
---------

In reference directory with "_V" suffix.  So bb.c is stored as "BB.C_V".
RCS documentation for unix says ",v" rather than "_V".

Locking
-------

Done in reference directory with suffix "_LOCK".  So when bb.c is checked
out, there is a file "BB.C_V_LOCK" in the reference directory during the
time that the checkout is being done.


code chgs. from unix version
----------------------------

1. #include <sys/time.h>

2. char *Klog = "log";

vs

   char Klog[] = "log";

extern char Klog[];
extern char *Klog;

3. Keyword array of struct including pointer to "Author", "Log", etc.

4. hardcoded directories "."  "/bin/sh" "/tmp/"

5. lock suffix, RCS file suffix, RCS file directory

6. subroutine fastcopy(), getusername() modified

7. run() uses com files for redirected output.

8. tmp file names standardized to RCS__*.tmp

9. mail interface on unlock fixed for vms/mail

10. advanced Suffix in initadmin() in rcsfnms.c so proper comment
header is guessed.

11. use vax rtl routines fprintf and fputs

12. chg curlogmsg from extern char *curlogmsg to char curlogmsg[logsize]
for error in rcs when deleting revision....

13. Remove all chmod calls.  CO without lock doesn't give you a
read-only copy of the file.

14. Add vms rename() fxn as a system call to a com file.  When on diff.
devices, do a system call to a Copy command in a com file.

15. Make the Lock file a temporary file that is deleted on closure by vms.
