I am pleased to announce that I have ported my AOS/VS Dump File Reader from C to PL/1 using ISPLI.

The program examines and/or loads DUMP files created under the old Data General AOS, AOS/VS and AOS/VS II operating systems.

You can find the source here: Steve's Data General MV Archive - AOS/VS Dump File Loader

Porting the code was a great way to relearn PL/1 after a very long gap indeed; I hope I have been reasonably idiomatic in my use of the language. Many of the DG utilities were orginally written in PL/1 so there seems to me to be a certain symmetry in coding this in PL/1
