Now that I've established the proper forum for postscript
questions (thanks to the 200,000 replies to prior question)...
We're running SunOS 4.1 with OpenLook 2.0 window manager.
I want to modify the OpenLook init.ps file so that I can
check the value of an environment variable (in postscript
language of course) and take appropriate action.
Something along the lines of:
(1) get value of env variable (e.g. LOGO)
(2) if (LOGO == 1)
run some post-script file
else
continue on
Not knowing post-script and not finding any sample post-script
code in the ~openwin directory that does something like this, I
was hoping for some suggestions...

Since the getenv operator returns an error if the environment variable doesn't exist, ?getenv should be used instead to provide a default. Also, getenv returns a string, so a cvi should be performed or a string compare should be done: (LOGO) (0) ?getenv (1) eq { (somefilename) run } if should work. ...jim
