Sat 23-Jan-93: As all Turbo Pascal users know to our common chagrin
the different Turbo Pascal version TPUs are not compatible across
the versions. I have made a Turbo Pascal 7.0 real mode compatible
rendition of my Turbo Pascal units garbo.uwasa.fi:/pc/ts/
tspa3170.zip.

   Since some users may ask, I am not going to make protected mode
nor TPW compatible versions. Protected mode programming has quirks
of it own, and is thus specialized. As for TPW, I do not use Windows
myself, and have thus no real interest of supporting it.
  The other, non-updated versions are
