IF/THEN/ELSE/ENDIF

FUNCTION

This command conditionally performs one or more commands.

SYNTAX

IF condition THEN
      command [command] ...
[ELSE
      command [command] ...]
ENDIF

condition: an expression or statement that is tested to determine whether an action will be taken.
command: any Script-IV command.

NOTES

The logical condition is two or more values, consisting of constants, data names, variables, functions, or expressions, that interact with relational or logical operators to form a true or false result.
For more information on logical conditionals see the section on Logical Conditionals in this manual.
One or more commands can be specified in the THEN clause. These commands are executed sequentially when the condition is true.
The ELSE clause is optional and can specify one or more commands to be executed when the condition is false.
Each IF must have a corresponding ENDIF.
The commands can be any Script-IV command, including other IF/THEN/ELSE/ENDIF commands.

EXAMPLES

IF CUS-CODE <> "Cash  " THEN
   DO 7-CUST-READ
   IF TERM-KEY = 4 OR  INPUT-FLAG <> " " THEN
      TERMINATE PROCEDURE
   ENDIF
ENDIF
