print from a different frame

#28 (closed) allowed us to show variables after manually changing the frame for a deeper inspection. GDB's expression handling also allows to print from a different frame - that would be nice (so not a big priority) for cobcd, too.

cp audit already shows the full path, ending with the program, for example

W101-AUDIT//W101-MAIN/W101-PARM/PROGA

the only option to show that from PROGC is to show the backtrace bt, then look where PROGA is in there, then change to that frame f 5 then cp audit then manually swith back f 0.

GDB's variant would be: p PROGA::audit, no manual frame switching needed. Maybe cprint can support the same, looking for COBOL programs (or user functions) with the name before ::, internally switch to that frame, do its logic, then switch back?
