TAPE HEADER by J.A. Slater from Sinclair User #16 (July 1983) J.A. Slater of Bury, Lancashire has written a very useful utility program for the 48K Spectrum. Tape Header uses a small machine code sub- routine to load the header data on a tape, then outputs that data to the screen. Details of the length of data, the program name, start address - bytes only - and the auto-start line number - Basic programs only - are all given.
