No value is passed into the function for the parameter nor is a value returned for the parameter when the function ends. Neither parameters are available for use as local variables within the function.
Note: Neither parameters are, in some instances, preferable to WRK context variables. WRK context variables are global to the function and can be updated inadvertently from internal functions within the main external function. The local nature of Neither parameters avoids this potential problem.
The following table shows the types of function parameter usage.
