Fixed Parameters

The first three parameters of the program are fixed. These are data structures that are passed throughout the LANSA generated applications:

...

You must not vary the content of any of the storage locations defined by these data structures. Any attempt to do this may violate system integrity and produce unpredictable results.

Arguments / Return Value Parameters

BIF arguments and return values defined in file DC@F48 are set up as parameters for the BIF program or subroutine.

Each of these parameters is passed with accompanying parameter(s) (i.e. every entry in file DC@F48 actually causes two (2) or four (4) parameters to be set up and passed to the Built-In Function program or subroutine).
