Functions   

Functions can be used in all three calculators in ILWIS: MapCalc, in TabCalc, in scripts or in the pocket line calculator. Some 50 internal functions are available (see also MapCalc and TabCalc), but also user-defined functions can be created.

A user-defined function generally contains of a combination of:

• existing MapCalc/TabCalc operators and functions, and
• user-defined parameters which represent maps and/or columns on which the function will be applied later on.
