IBM ILOG Script functions

In IBM ILOG Script, functions are regular values (also known as first class values) which can be manipulated like any other type of value: They can be passed to functions, returned by functions, stored into script variables or into object properties, and so on.

For example, the function parseInt is a function value which is stored in the parseInt variable:

parseInt -> 
a function value 

This function value can be, for example, assigned to another variable:

myFunction = parseInt 

and then called through this variable:

myFunction("-25") -> -25 

Function methods

There is only one method of functions.

Table 1. Function methods
