Try this:

IDL> spawn,'ps | grep idl | grep -v grep',result,/sh
IDL> print,result
23847 pd S 0:02 /usr/local/rsi/idl_4/bin/bin.sunos.4.1/idl
IDL> print,long(result)
23847

If you really feel lucky you can try something like......

IDL> ; check your libc version before doing this!
IDL> result=call_external('/lib/libc.so.1.9','getpid')
IDL> print,result
23847
