Begin, Again The comparison is case-insensitive, so 'CAT' = 'cat' unless you have altered the CompareCtrl setting. The If command does not set the $Success variable! In deference to the ingrained training of seasoned programmers, you may use the word ―then‖ after the comparison. Thus, the following command will be accepted: If x > y then z = 'Hello' This usage is non-standard, however, and is not recommended. The scripting engine treats the ―then‖ as a variable, but ignores it in this context. Thus, you should never use a variable named ―Then‖. The If command does not have an ―Else‖ option as in most programming languages. To execute a command when the If condition is false, use the Otherwise command. Alternatively, you can use the Begin command with an Else section. Otherwise Format Example Purpose Parameters Restrictions Similar Cmds Otherwise c1 If Animal = 'Cat' Type = 'Feline' ; The initial If command Otherwise Type = 'Non-feline' ; Action taken if false Executes an alternative command when the If comparison is false c1 - Command The Otherwise command must follow immediately after an If. The Otherwise command may not be combined with a command that defines the start of a code block, such as Begin or FileInit. Else Procedure Format Example Purpose Parameters Restrictions Procedure v1 Procedure MyCode Defines the start of a generalized section of script code, which is terminated with the End command v1 - The name of the Procedure (must be a simple variable) Recursive procedures (i.e. procedures that call 106
