FDUMP - do a symbolic dump of a program.

Usage:

call fdump(levels, unit)
  or
call fdump

Where:

levels
is the number levels up the call stack are to be dumped.
unit
is the unit to write the symbolic dump to. Unit 6 is always a good choice.

Description:

FDUMP walks back up the call chain producing a symbolic dump (variable name and value) at each subroutine that was compiled with the FDS debug tables. If called with no arguments, it dumps the whole stack to unit 6.

In batch, a very useful debugging technique is to specify FDUMP as one of the wrapup routines.
