ŒID ID Number


The niladic system function ŒID returns a single integer which is the System ID Number.

To provide security for applications and packages written to run under APLX, ŒID, can be used to query the system identification number. Each APLX interpreter has a unique identity code.

This feature (used, of course, within a locked function) could help prevent unauthorised use of software by detecting the use of a function on an unauthorised system and taking appropriate action.
