SHOW SUB-PROGRAM INTERFACES

Syntax:

SHOW SUB-PROGRAM INTERFACES [ : <sub-program> ] DO NOT SHOW SUB-PROGRAM INTERFACES

Function:

The sub-program declaration statement is printed, followed by its data type if it is a function, followed by a list of the arguments (if any) and their attributes.

The COMMON blocks and modules referenced by the sub-program are then listed. For each COMMON block or module, fpt lists the variables which are used to import data to the sub-program and to export data from it. A variable is considered to import data if both:

it is read by the sub-program, or by any other sub-program which is called directly or indirectly from it;
it is written to by any sub-program which is not in the call tree below the current sub-program.

A variable is considered to export data from the sub-program if both:

it is written to by the current sub-program or by any sub-program called directly or indirectly by it;
it is read by any sub-program which is not below the call-tree of the current sub-program.

Note that by taking the call-tree of the sub-program into account, fpt reports the entire data interface of the sub-program.

If no sub-program name is specified in the command, fpt reports the interfaces of all sub-programs.
