Conditionals

How does a conditional work (the 88 thing)? by GC1CEO
Posted: 20 Feb 01

An example of a conditional would be:

05 STORE-CODE PIC XX.
        88 BOSTON         VALUE 01.
        88 NEW-YORK       VALUE 02.
        88 TORONTO        VALUE 03.

In this example, when you get down to a usual IF statement, without using a conditional you might say something like:
 
IF STORE-CODE = "01"

However using a conditional, you could do the exact same thing by typing:

IF BOSTON

This makes a lot easier when it comes to ever yes/no questions in a program or where there is a long list of different options (easier to create a name for each option versus remembering/writing down the values and what they mean).
