This document describes the Random ISZ Test, a diagnostic program for the PDP-8. It operates in two parts: Part 1 selects FROM, TO, and OPERAND locations using a random number generator (with options to hold these values constant), while Part 2 uses a fixed set of these values. The program is designed to test the functionality of the ISZ instruction and provides detailed error reporting including failure analysis and a scope mode to aid in debugging specific error conditions.
