FYLHLP - PS/8 File Utility Program

FYLHLP is a utility program for PS/8 systems that helps programmers maintain file systems and debug file-handling code. It is composed of two main parts:

• HELP: Interfaces with the system Command Decoder to list directory entries, including empty ones, and can transfer control to the second section.
• FYLLUK: Allows the user to examine, modify, and search through data blocks on a file-structured device using octal addresses.

The documentation provides instructions on various operational modes, including search limits and masks, methods for modifying block contents, and procedures for returning to the system monitor.
