This document serves as a diagnostic program manual for testing the Jump to Subroutine (JMS) instruction on the PDP-8E. The program randomly selects memory addresses to execute Jump (JMP) and JMS instructions, verifying successful completion through the interrupt function. If an error occurs, the program triggers a halt and provides detailed error printouts to help the user identify the location of the JMP and JMS instructions, the target address, and the state of the program counter at the time of the interrupt. The document includes detailed operating instructions, control switch settings, error recovery procedures using a scope mode loop, and execution time information.
