IF condition GOTO label;

IF NOT condition GOTO label;

Syntax Description

condition: is the test that is performed to determine whether a set of statements should be executed.
label: specifies a labeled statement in the script.

Details

The IF statement conditionally jumps to another statement in the script. The IF statement can check two conditions: connection type and whether the script has been called by the SIGNON or the SIGNOFF command.

If the statement is testing for sign-on or sign-off, condition should be one of the following:

SIGNON: specifies that the SIGNON command invoked this script.
SIGNOFF: specifies that the SIGNOFF command invoked this script.

If the statement is testing for connection type, condition should be either FULL SCREEN or one of the values for the COMAMID= system option.

The value FULLSCREEN can be used to detect any full-screen 3270 connection. The remaining values correspond to values for the COMAMID= system option. For more information about COMAMID= values for emulation software, see COMAMID= System Option.

label must specify a labeled statement in the script. For example, in the following IF statement, ENDIT is a label that is followed by one or more statements that terminate the link when the user has issued a SIGNOFF command:

if signoff then goto endit;
