Building LAP6-DIAL Sources Program Description

This document serves as an identification and procedural guide for the BUILDING LAP6-DIAL SOURCES Program. It introduces LAP6-DIAL as an integrated editor, filing system, and assembler specifically designed for the PDP-12 computer. The document clarifies that the editor and filing components were developed from the basic LINC program LAP6 by Mary Allen Wilkes, with the assembly portion derived from PDP-8 programs such as PAL-D. Digital Equipment Corporation extends its appreciation to Mary Allen Wilkes for her foundational work.

A significant part of the document outlines a detailed, multi-step procedure for assembling the DIAL-MS system, which encompasses all associated system programs and routines (e.g., CREF and GENASYS). This assembly process involves loading DIAL-MS, then systematically transferring and copying specific data blocks using the PIP utility across various storage units (tape or disk), interspersed with execution of several assembly commands. The document also mentions the SLOWCREF program, available through DECUS, for generating cross-reference listings of the system programs, detailing the necessary hardware requirements (16K of core and 3000 scratch disk blocks).
