SDUMP subroutine

The SDUMP subroutine provides a symbolic dump that is displayed in a format dictated by variable type as coded or defaulted in your source. Data is dumped to the error message unit. The symbolic dump is created by program request, on a program unit basis, using CALL SDUMP. Variables can be dumped automatically after abnormal termination using the compiler option SDUMP. For more information on the SDUMP compiler option, see VS FORTRAN Version 2 Programming Guide for CMS and MVS.

Items displayed are:

All referenced, local, named, and saved variables in their Fortran-defined data representation
All variables contained in a static common area (blank or named) in their Fortran-defined data representation
All variables contained in a dynamic common area in their Fortran-defined data representation
Nonzero or nonblank character array elements only
Array elements with their correct indexes

The amount of output produced can be very large, especially if your program has large arrays, or large arrays in common blocks. For such programs, you might want to avoid calling SDUMP.

Syntax

CALL SDUMP [(rtn₁,rtn₂,…)]

rtn₁,rtn₂,…: Names of other program units from which data will be dumped. These names must be listed in an EXTERNAL statement.
