This CD-ROM contains MAS/MILS data. It has been produced in accordance with the ISO 9660 standard for CD-ROMs and is therefore capable of being read on any computing platform that has appropriate CD-ROM driver software installed. However, the data has been compressed and requires GSSEARCH software for access. GSSEARCH, supplied on the CD-ROM, runs only under DOS.

The root directory contains the information file 1ST_READ.ME and INSTALL.EXE. The CD-ROM must be installed on your computer prior to use. To do so, switch to your CD-ROM drive, and run INSTALL. The process will create a MASMILS directory on a chosen hard disk and will copy a menu system to that directory. You may invoke this menu system by entering the command MASMILS from the MASMILS directory on your chosen hard disk drive.

Several DOS subdirectories are on this CD-ROM. Their names and the information they contain are listed below.

  \MASMILS Contains the MAS/MILS data, index files, and configuration file required by the GSSEARCH software.
