Your library list may not contain the program you placed the breakpoint in. Try adding the library for the "PGMNAME" with the breakpoint to the top of your library list. -----Original Message----- From: c400-l-bounces+gary.monnier=powertech.com@xxxxxxxxxxxx [mailto:c400-l-bounces+gary.monnier=powertech.com@xxxxxxxxxxxx] On Behalf Of Boris Sent: Wednesday, May 31, 2006 5:12 PM To: c400-l@xxxxxxxxxxxx Subject: [C400-L] Debugging Hi All I have a program which is called from a main program by the "system" function: system("CALL PGMNAME"); Does anybody know why the debugger doesn't stop on a breakpoint set in the PGMNAME? I have no problem to stop in the calling program. I tried to compile the called program with Activation group *caller but it didn't seem to help. Thanks in advance.
