POST Library Maintenance System
The POST system was the system for managing programs on magnetic tape,
and predated the arrival of disc drives on KDF9s, which then led to PROMPT on the
time sharing systems and of course the EGDON system.
The Kidsgrove Algol Compiler that we have was originally embedded as part of the POST system.
We have scanned copies of the original documentation.
The POST system is
documented in the Algol Users Manual
The PROMPT system is
documented in the Service Routine Library Manual
