CROSSREF Manual

RUNNING CROSSREF

Interactive Mode

CROSSREF operates in interactive mode when you omit both the IN

file-name

option and the

command-list

parameter from the CROSSREF

command.

When run in interactive mode, CROSSREF sends the following

product banner to the terminal:

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

T9622C00 is the product number and version of CROSSREF.

(15JUL87) is the release date for this version of CROSSREF.

CROSSREF also displays the name of the system you are using at

the end of the banner.

CROSSREF then displays an ampersand (&) prompt to indicate that

it is ready to receive commands. When you enter a command,

CROSSREF executes the command or displays an error message. It

then displays another ampersand and waits for additional input.

This procedure continues until you enter an EXIT command or press

CTRL/Y, the End-of-File (EOF) command.

You can enter more than one CROSSREF command in response to

the prompt (&), but you must separate multiple commands with

semicolons. For example, the following two sets of commands,

which tell CROSSREF to scan the file named PROGRAM and generate a

listing to the file named CROSS1, are equivalent:

&SCAN program; GENERATE /OUT cross1/

&SCAN program

&GENERATE /OUT cross1/

CROSSREF executes commands one at a time from left to right.

If CROSSREF encounters an error, it stops processing the command

line. CROSSREF, however, executes all commands up to the point

of the error.

You can continue commands for more than one line by typing a &

at the end of the line. CROSSREF prompts for the remainder of

the line before executing the command. When CROSSREF receives

a line without an ampersand at the end, it executes the command

immediately.

Command lines, continued or not, cannot exceed 528 characters.
