This package contains an experimental implementation of the IEEE 855 (MOSI) standard interface for CP/M-80, together with a language interface for Pascal MT+. MOSI stands for "Microprocessor Operating System Interface". The purpose of the MOSI Standard is to define a set of standard "system calls" to access various operating systems in a uniform way. This implementation is intended as a model for MOSI operating system interfaces and language interfaces, as well as a useful set of enhancements for CP/M in its own right. Many of the files in this distribution are compacted by the public domain SQUEEZE program. These files are identified by a Q as the second character in the filename extension. To recover the original source, run the USQ (UNSQUEEZE) program which is included. For example: USQ C: MOSICPM.DQC This will produce MOSICPM.DOC, which is the primary documentation for this package. The drive specification, which is optional, will route the result to a different disk which should have sufficient room. Some of the source files on this disk are Copyright 1985 by James D. Mooney.
