Additional 0S8 Utility Programs with CCL Calling Sequence

摘要

A system for labelling the directories of magnetic media (rigid discs, floppy discs, cassettes and tapes) in a machine readable fashion, a go-nogo quick machine test program and two new versions of a text printing program are presented. Also presented is a method of calling these utility programs using the commands PRINT and ZERO. Two versions of the text printing program allow either a raster-scan plotter or a conventional printer to be used. The plotter version allows the font to be modified and figures to be included in the test. It also includes Greek characters, mathematical symbols and shifted text. (Author)
