Beyond being written in Applesoft BASIC as I noted elsewhere, TASC's coverage of BASIC keywords is almost entirely complete, going by chapter 7 of the manual. Any given Applesoft program has a very high chance of successfully compiling out of the box, and the very few differences with the interpreted language can be easily worked around (if the `DIM` command is any indication). As one used to aftermarket compilers that only support subsets of the language, TASC's comprehensiveness is very, very impressive.
