Abstract: FORTRAN IV On-Line Debugging Tool (FODT) is a

subroutine which allows the programmer to examine/modify memory

contents and monitor program flow at run time. It provides the following

facilities: examine/modify memory contents in octal, decimal or ASCII

formats; set program break-points at entry or exit points of subprograms;

set break-points at prescribed program lines; find addresses of main

program and subprogram entry points; examine subprogram argument

addresses and contents; trace subprogram callers on program break; and a

HELP routine.

FODT is composed of a set of relocatable modules which are loaded

with the user program. Is is invoked by a subroutine call at the beginning

of the mainline program.
