Customizing the User Environment

GOTO

Use GOTO to execute a portion of the login script out of the regular

sequence.

Command Format

GOTO label

Use label to indicate where the login script should continue executing.

Using GOTO

Set BREAK ON in your login script before experimenting with GOTO loops

so that you can break out of a login script if necessary.

For more information about the BREAK login script command, see

“BREAK” in this chapter.

Do not use GOTO to enter or exit a nested IF…THEN statement. This usage

confuses the program.

Example

To execute a loop of commands, you could include the following lines in

your login script. In this case, the commands to be executed are labeled

AGAIN (as indicated in the second line).

SET X=“1”

AGAIN:

SET X=<X> + “1”

;see compound strings for this

WRITE <X>

IF <X> < “9” THEN GOTO AGAIN

The GOTO command looks at the value of <X> (a DOS environment

variable). If the value of <X> is less than 9, then <X> increments by 1 and

GOTO loops back to the AGAIN label. When <X> gains the value of 9, the

IF…THEN test becomes false, the GOTO is ignored, and the script

continues normally. See the IF…THEN command next.
