The philosophy behind PARADYME is that the user generates a system as a set of separate modules which are then linked together as desired. However, adopting this approach, there will be occasions when the user wishes to pass information from one routine to another in the system. This can be achieved in several ways. However, the two standard forms used in programming are via the COMMON area and via a parameter list. PARADYME allows the user to choose either or both of these methods by utilising the following 2 parameter entries.

In the sub-sections which follow, each aspect of Interprogram communication is covered in more detail.
