# FILE 0 for the Oliger Disk System

A BASIC type-in program for the Timex/Sinclair 2068 that reads the CATalog of an Oliger disk and displays a navigable directory with cursor movement and a file-load option. The program is noted as tight on memory and makes use of BASIC keyword tokens to save space.
