What it means for a program to have (or not have) this capability

IA Interactive Access Yes Programs with IA capability can be executed interactively. That is, if you log on interactively (with a "HELLO" command), you can execute programs that have IA capability. If the program does not have IA capability, then it cannot be executed from a session.

BA Batch Access Yes Programs with BA capability can be executed by batch jobs. If a program does not have BA capability, then it cannot be executed by a job (one that logged on via a "JOB" statement").

DS Data Segment No Programs with DS capability can use intrinsics to allocate extra memory in the form of extra data segments.

PH Process Handling No Programs with PH capability can use intrinsics to run other programs, thus creating additional processes.

MR Multiple RIN No Programs with Multiple RIN capability can hold more than one Resource Identification Number. This creates the potential for "deadly embraces," which can require that the system be rebooted.

PM Privileged Mode No Programs with Privileged Mode capability can access system internals. PM capability is required to use the Architected Interfaces.
