Aubit4GL allows you to define a CONSTANT in one place (for example to define an array size) then refer to it throughout all the modules in a program. To increase the array, simply edit the DEFINE CONSTANT statement and recompile. In standard 4GL, you have to find every instance of the value of the constant and change it before recompiling with the risk of having missed some.

Syntax:

DEFINE CONSTANT pi 3.1415923
DEFINE CONSTANT codemax 256
