CEDF is a CICS supplied debugging facility which will insert breakpoints at every CICS instruction. Expeditor on the other hand allows you to insert breakpoints at will.
CEDF displays only those values in EIB. Expeditor allows you to display values of all fields.
Expeditor allows you to skip certain lines during execution. CEDF does not allow this.
Expeditor allows you to debug background tasks as well, i.e. tasks that are not terminal specific. CEDF would not allow this.
Could you please provide more information on what you mean by changing map fields dynamically. Is it in expeditor or in the program or something else.
I am assuming your question is how to change the values in map fields using expeditor.
Two ways to do this:
1. Find the variable in the working storage and hit a K next to hit. This would permanently display the value during execution. Now place a breakpoint before the map is sent. During execution, when the code stops at this breakpoint, change the value and then press PF12 to continue execution till the next breakpoint.
2. Place a breakpoint at the line that populates the map field. During execution, when the code stops at this breakpoint, press PF9 to execute this line and stop at the next line. Now, the value in the map field is displayed at the top of the screen. Change the value and then press PF12 to continue execution till the next breakpoint.
