The documentation available describes a method for seg-

menting PDP-8 programs for the purpose of facil itating pro-

gram maintenance and residence in MTS (Michigan Terminal

System) files. The method provides for program storage on a

page-relocatable basis with relocation information contiguous

to but not necessarily integral with text information.

Linkages between separately assembled program segments

are provided in a form very similar to those used in IBM

System/360 systems.

Currently available utilities within MTS provides assembly

and link-editing facilities, using programs stored either as

punched card decks or in MTS files. Utilities are also in-

cluded for the purpose of paper tape transcription either in

PAL-compatible format or in a special format useful for

dynamic loading via a data link to a remote machine. In

addition to these MTS utilities, two relocating PDP-8 loaders

are available which operate using the special dynamic-

loading format. Each of these programs occupies one ded-

icated page of PDP-8 memory and operates in a multicore-

bank environment. One of these programs is designed to

operate as a stand-alone utility, while the other is designed

to operate within the RAMP system.
