     Tried out the above on our IIgs with STRUCTURED BASIC downloaded from
USA2WUG, kind of neat!

     One weirdness is that, after starting SBASIC, EXECing the Text file copy
of your program does not produce a correctly parsed SBASIC program. For
example, the SUPERIMPOSE command in Line 50 becomes

50 SUPERIM POS E

and the TEXTMODE command in Line 70 becomes

70 TEXT MODE


     Evidently EXEC gets handled by Applesoft with no adjustments to
recognize SBASIC commands. There was no problem with SAVEing and LOADing
programs.
