Hi,
I'm using a KCL interpreter under unix and a newby in Lisp and was
asking myself if there are commands like the ones in C:
* "system" to make a call to a system command or an executable
and
* "popen" to use the output or input of an executable as a file
with "read" and "write" commands.
And more generally, where could I find help on system dependent
Lisp commands (that wouldn't be in Steele's Bible)?
I would be grateful for any help,
Eric

It's nice that there are so many dumb people on Earth,
I feel more intelligent.

You should be able to find some documentation in the KCL sources,
if it hasn't been made available in some other way at your site.
There is a system function. For instance, you can write
(system "ls")
"popen" and the like are harder. Some versions of KCL (such as
GNU Common Lisp -- GCL) have something along those lines built in.
It's not too hard to write such things yourself using the C code
facilities of KCL, but it's a bit tricky. I have some code I could
probably make available that might help. Let me take a look...
