                    The Microdrive File



     Kathleen Peel with more on Sinclair's Microdrive.



[ This article was, evidently, one part of a series on the

  Microdrive. Only a small part concerned the program

  which was printed with it, and that is the only part

  that is reproduced below.

  Note also that the program does not, in fact, deal with

  Microdrives at all. It does require an Interface 1 to be

  connected, though, because it uses that device's features

  to handle the extended syntax. Note also that, due to the

  fickle nature of this device, the command described might

  not work unless you *first* use any of the Interface 1's

  own extended command and only then install the new one. ]



  This month I have produced a very simple "memory free"

command that will enable me to explain two of the problems

encountered in producing this type of command as opposed to

the graphics command of the previous article. I have chosen

the command

        PRINT *

to provide the 'memory left function'.
