Syntax 

NUM-PARAMETERS ( integer-expression )

integer-expression

An integer expression indicating the number of parameters expected. The default is zero.

Whenever NUM-PARAMETERS is set, all existing parameters, including those from earlier uses of SET-PARAMETER, are cleared and deallocated.

If there are parameters to be passed, NUM-PARAMETERS must be set before the INVOKE( ) method is executed.

When you are getting a parameter, set NUM-PARAMETERS to the actual number of parameters to be passed, which might vary if one or more trailing parameters are optional.

When you are setting an attribute, use NUM-PARAMETERS 1.
