Use GOTO to execute a portion of the login script out of the regular sequence.
Set BREAK ON in your login script before experimenting with GOTO loops so that you can break out of a login script if necessary. See Section 3.7, BREAK.
IMPORTANT:Do not use GOTO to enter or exit a nested IF...THEN statement. This usage causes problems for the program.
Use label to indicate where the login script should continue executing.
In Windows, the label can take formats :label (colon before) or label: (colon after). When the colon comes before the label, any words may be used with the label. When the colon comes after, do not use words that also represent a command or they are interpreted as a command.
To execute a loop of commands, include the following lines in the login script. In this case, the commands to be executed are labeled AGAIN (as indicated in the second line).
SET X=<X> + "1"
;see compound strings for this
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.
