A debugger feature plea:  When in debug mode, provide an "AddAddrBkp" cmd. When an address range is referenced in the job being debugged, call a debug handler pgm.  Similar to the action of the breakpoint handing pgm that is called when an instruction is executed.
 
===> that may be hard. The way the orignal breakpoint (BRK "here") is by compiling into a dummy instruction.
Is you ADDBKP "here", the dummy instruction is actually replaced in the program object by a trap instruction.
 
 
Leif,
 
When you AddBkp, a trap instruction is inserted in the pgm object?
 
What happens when the pgm is called by a non debug mode job?
