XREF Command

XREF is an interpreter command that generates a cross reference of the

entire current program, just the main program unit, or any procedure or

function of the current program. A cross reference is a list of the

identifiers in the specified part of the current program that includes

the following information: name, type, class, and line numbers on which

it is used. The cross reference is sorted according to identifier names.

Syntax :

[WITH LIST ]

XREF [

sub_name

[

,sub_name

]...] [WITH SOURCE] [TO

listfile

]

Parameters

sub_name

Either MAIN or the name of the procedure or function for

which the cross reference is to be generated. A cross

reference is generated from the entire program if this

is not specified.

WITH LIST If this parameter is specified, the cross reference

WITH SOURCE immediately follows the listing of the source code for

each individual part (MAIN, procedure, or function). If

it is not specified, the identifiers from the main are

listed under a banner containing the word MAIN, and

identifiers from each procedure or function are listed

under a one-line banner with the name of the procedure

or function.

listfile

The name of the file the cross reference is to be

printed to. If not specified, the cross reference is

printed to the destination specified by the SEND SYSTEM

OUTPUT TO statement (usually the terminal).

The cross reference is generated on a subunit basis. The following

information is provided for each identifier:

Name Name of the identifier.

Class Class to which the identifier belongs. Class

information is designed to convey dimensionality and

usage information. Dimensionality is specified by

SIMPLE, identifiers declared implicitly or explicitly as

scalars, and array identifiers declared implicitly or

explicitly with the DIM statement as arrays. For
