AAEC facilities to aid in the development of FORTRAN programs

Abstract

Two subroutines, DBGON and DBGOFF, designed to give users more control over the debug options supplied with the IBM360 FORTRAN IV [G] compiler are described. Examples of the use of these subroutines in the debugging of a FORTRAN program are presented. Macros developed to simulate FORTRAN I/O in Assembler programs are also described, and their value to programmers converting FORTRAN programs into Assembler language routines is demonstrated.
