I played around with it recently. It seems pretty nice. I tried compiling an
Object Pascal program I'd written for MPW Pascal, and noticed 6 "differences"
right away:

- TML Pascal is smaller. MPW Pascal is about 300K, TML about 140K

- TML Pascal is faster. I don't have specific compile times, but the time
savings is significant. Roughly, I'd say TML is 1.5 to 2 times faster.

- TML Pascal MUST have compiled Units in the USES statement. For this reason,
you can't have circular USES between multiple units. In my case, I had to
reorganize my program significantly.

- The interface files that come with TML don't have the nice conditional
compiler statements that MPW 3.0 Pascal's do. In MPW, you can specify your
interface files in any way that you want. If file is USED before a dependant
file is USED, then it calls it in automatically. This way, you can specify only
the files you need and in any order you need. TML's is not like this. You have
to specify all the interface files ever used, and in a specific order.

- TML Pascal doesn't link with MPW 3.0 linker with object optimization turned
on. In my sample, the resulting code started jumping to the method tables!

- Short circuit boolean operators don't seem to work.

TML Pascal comes with the full MPW 3.0 System. It doesn't come with MPW Pascal
C, Assembler, or SADE. It does come with the Shell manual, but not for ResEdit
or MacsBug. Finally, it doesn't come with the groovy binders and tabs that
MPW does.

MPW 3.0 final has been available since MacWorld. Call APDA at 800-282-APDA.
