SHOWMAP is an ISPF EDIT MACRO which invokes Don Faville's CICS MAPPRINT program
for the member you are editing and presents you the results on-line. So, if
you're editing some BMS source, and you want to know what the map basically
looks like but you don't want to go to CICS to see that, just type SHOWMAP on
the command line and press .
The MAPPRINT program will then operate against the BMS source member you are
editing, and when finished, will bring you into an edit session of the report
generated by the program. You can print this fairly easily at this point by
typing PRINTIT and pressing .
