Example: L:\>go lan (where "L" is the CD-ROM drive) Note, the "LAN" option will affect the speed of the software to be much slower. 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴쩡컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� � Using The CD-ROM � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� The SSTF 12 software runs on personal computers with 640K RAM operating under MS-DOS 3.3 or higher. There are no special display requirements. The CD-ROM is in the ISO 9660 format which requires the use of Microsoft CD-ROM Extensions Version 2.0 or higher. At either the opening screen or at the data display screen, there is an option to display the files found in the sub-directory, DOCUMENT (e.g. Software features, Record Layouts, Appendixes etc.).
