I am trying to run an ILE CL program in debug mode on one of our test boxes. I have run debug zillions of times, no problem. But something very strange is occuring, and what makes this even more odd is that I had this program successfully running in debug yesterday morning on the test box. It will run on our development box in debug, my co-worker can run it in debug on the test box. But for some reason, it will no longer run for me. Here is what happens: When I issue the command, STRDBG PGM(MYLIB/MYCLPGM) UPDPROD(*YES), all is well. The module source displays. Until I hit f10 and then issue the command to run the program: CALL PGM(MYLIB/MYCLPGM) PARM('9999'). Instead of going into the source and allowing me to step thru the code, the program takes off and runs. I still have to do an ENDDBG also before I attempt to put it back into debug mode again after this. If anyone has ever seen this occur before, information would be greatly appreciated.
