FUNCTIONS ON User-defined functions

Notice that the default setting for KEYWORDS and LITERALS is

See Section 4 for details.

SAMPLE LISTING

The following example starts CROSSREF, scans the file named

BASEX, and generates a listing to $s.#lp:

13> CROSSREF

CROSSREF-CROSS-REFERENCE PROGRAM-T9622C00-(15JUL87)

&SET LANGUAGE basic

&SCAN basex

&GENERATE /OUT $s.#lp/

&EXIT

14>

On the following pages, you can see the program and its cross-

reference listing. The listing includes line numbers, variables,

functions, and system variables. It does not include keywords

and literals, however, because only the default settings were

used.
