A utility program which enables the user to load, examine,

and modify computer programs by means of the Teletype.

This program is a revision of the program written by A. D.

Hause, Bell Telephone Laboratories. Extensive use of the

program has suggested many refinements and revisions of the

original program, the most significant additions being the

word search and the breakpoint. The standard version of

OPAK is stored in 6200 to 7577 and also 0006. An abbreviated

version is available (7000 to 7577, 0006), which is

identical to the other except that it has no provision for

symbolic dump. Both programs are easily relocated. Control

is via Teletype, with mnemonic codes, (e.g. "B" for inserting

breakpoint, "P" for proceed, etc.).
