The best way (that I know) without using a C function includded in the runner, is: $ fglgo myprog.4gi $$ # (passing the process Id as first argument) and inside the prog ... INTEGER pid ... LET pid = fgl_argval(1) ...

If your shell supports it, use $PPID instead of $$ and you get the PID of the parent. (See my other posting). > $ fglgo myprog.4gi $$ # (passing the process Id as first argument) > LET pid = fgl_argval(1) If you do it this way you get the *parent* PID of your 4gl- application (i.e. of your shell).
