Calling "nice" from MF-COBOL on the UNIX platform

Does anyone happen to have a sample of code where you've called the
"nice" function to give the current process a higher priority on the
system? I know it can be done, but am having trouble pinning down the
exact syntax/parameters of the call.

System Information
------------------
OS:    HP-UX 11i
COBOL: MF OC 4.2

Thanks in advance for any/all assistance.

Chris

Stephen,

Thank you. Your post is exactly the information I was looking for.

01 PUFF-NICE.
3 NICE-GRUND            PIC X(07) VALUE "nice   ".
3 NICE-RUN              PIC X(65).      *> for programname
3 NICE-REST             PIC X(42) VALUE
">/dev/null>&2/dev/null& echo $!>".

01 MF-CBID.
3 MF-CB-ZEILE.
5 FILLER      PIC X(06)  VALUE "sh -c ".
5 FILLER      PIC X(01)  VALUE X"22". *> "
5 W-CMD-RUN PIC X(99).
5 FILLER    PIC X(01)   VALUE X"22".
5 MF-CMF-N  PIC 99 COMP VALUE 00. *> end

for example you will start a program "stocklist"
in background mode, so you do

move "cobrun stocklist &" to nice-run.
move puff-nice   to   w-cmd-run.
call  "SYSTEM"   using mf-cb-zeile.

This is running on HP-UX 10.20 and Linux etc.
Depending on platform  the NICE-REST perhaps
NICE-GRUND can be a little different, but it is
no problem to fill it on begin of the whole application
with correct os-depending-values.
