Rsx Multi-Tasker

This document is a technical newsletter from July 1985 containing several articles related to the RSX-11M operating system. The contents include:

• The Bag of Tricks: MACRO-11: A column explaining how to capture and use task identification information (stored in registers R3 and R4 during initialization) for purposes such as version logging or communication between tasks.
• Building RPT for Faster Error Reports: A guide on improving the performance of the RPT (error log summary) program by building it with fewer or no overlays, including specific command files for implementation on an RSX-11M-PLUS system.
• Password Encryption for RSX-11M: A technical overview and implementation guide for adding password encryption to RSX-11M. It details the necessary modifications to build files and provides a sample assembly routine (ENCODE.MAC) to secure passwords.
• Recovering Files From a Damaged Files-11 Disk: A tutorial on emergency data recovery techniques after hardware failure. It includes the source code for two FORTRAN programs, FNDFIL (to locate file directory entries and header blocks) and RECOVR (to read and reconstruct corrupted text files based on retrieval pointers).
