  • The QL's Forbidden ByteQL Type-in program
    Those of us who “cut our computer teeth” on the ZX80/81 learned quite early about the caveat that accompanied any use of CHR$ 118 when machine code was stored in REMs. Like the Cheshire cat, the line could disappear right before your eyes till nothing was left but the grin! The problem was that this…
  • String Slicing, Coercion & ConcatenationQL Type-in program
    String concatenation is a subject that can’t easily be covered in a vacuum. It must include string slicing and coercion as well.
  • QL NetworkingQL Type-in program
    Claims abound for computer hardware and software. The original claims for SINCLAIR’S QL (aka ZX-83) promised the capability of a PEER/PEER NBTWORK because the QL had been designed for use in a “business” environment. The two ‘NET’ ports bear witness to this intent.

  • A Half Dozen or More TOS ToolsTS 2068 Type-in program
    This program was converted from Bill Jones “LKDOS TOOLS BY THE HALF DOZEN” published in the July issue. There are many differences between LKDOS and TOS.

    Why not use my TS-2068 Daisy software to set-up special print pitches and Letter Quality mode, and then throw the the A/B switch over to the QL for printing?
  • Printers and Printer ControlTS 2068 Type-in program
    The genesis of this work-up goes back to my early work with the Sinclair ZX-81, a computer designed “not to print”. Soon after the ZX-81 reached the “million mark”, cottage industry developed machine code “Printer Drivers”. From then until today, our Sinclair computer fans have not had a minimum diet of “How To Control Printers”.…
