Hello all,
I am trying to use the VAX Command Line Interface Runtime Routines
(CLI) from within a VAX Pascal program. The problem I am having is that
I can't seem to find the system file to include that contains all the
return codes for these routines. (e.g. CLI$_NORMAL, CLI$_PRESENT, etc).
Are these codes defined in starlet.pas or is there another file that
my system seems to be missing?
Any help would be greatly appriciated. Please E-mail replies.
Thanks in advance,
-- jogle

Sorry to post this solution instead of mailing it. I've already wasted
enough time trying to reach people without decent Internet or BITnet
addresses. Below is my solution to the question of communication between
VAX Pascal and CLI. CLI is the only decent way to get VAX Pascal to detect
command line parameters. We finally found the values of CLI$_PRESENT etc.
in a C include file (see comments below). Don't ask me why DEC didn't include
info like this in its documentation on CLI and CDU.
Good luck,

You could simply declare them as follows:
var
CLI$_PRESENT : [ external, value ] unsigned;
In general, in Vax/VMS, most such symbols can be resolved by two means:
1. during the compilation - for Pascal, that often means
[ inherit('SYS$LIBRARY:STARLET') ]
2. during the link - as shown above
For some groups of symbols, only one method is available.
