Using Fortran compiler listings

Fortran listings provide you with:

The date of compilation including information about the compiler
A listing of your source program
Diagnostic messages telling you of errors in the source program
Informative messages telling you the status of the compilation

Table 1lists of the contents of the various compiler-generated listings that you might find helpful when you use information in dumps to debug Fortran programs.

Table 1. Compiler-generated Fortran listings and their contents
Name	Contents	Compiler Option
Diagnostic message listing	Error messages detected during compilation.	FLAG
Source program	Source program statements.	SOURCE
Source program	Source program statements and error messages.	SRCFLG
Storage map and cross reference	Variable use, statement function, subprogram, or intrinsic function within a program.	MAP and XREF
Cross reference	Cross reference of names with attributes.	XREF
Source program map	Offsets of automatic and static internal variables (from their defining base).	MAP
Object code	Contents of the program control section in hexadecimal notation and translated into a pseudo-assembler format. To limit the size of the object code listing, specify the statement or range of statements to be listed; for example, LIST(20) or LIST(10,30).	LIST
Variable map, object code, static storage	Same as MAP and LIST options above, plus contents of static internal and static external control sections in hexadecimal notation with comments.	MAP and LIST
Symbolic dump	Internal statement numbers, sequence numbers, and symbol (variable) information.	SDUMP
