Disklook

Summary

DISKLOOK is a utility program designed for the PDP-8 computer with a 32-K DF32 disk drive. It allows users to interface with the disk via an on-line Teletype to perform the following tasks:

• Examination and Alteration: Users can examine disk locations by typing an address expression and modify the contents of those locations.
• Navigation: The program supports an "examine-next" feature, which allows users to view the current location followed by the next consecutive location.
• Search Operations: Users can perform positive and negative masked searches between specified address limits. Because the program does not buffer data, these searches are relatively slow.
• System Integration: The program includes error handling for illegal characters and disk errors, provides a method to return to the resident monitor via a control character, and occupies memory locations 200 through 777.
