That would require a partial BASIC interpreter.  CiderPress only does
as much as Applesoft itself would if you did an EXEC on the text file,
scanning and tokenizing.  Checking for syntax errors, incorrect variable
names, and so on, is more involved.

Essentially you'd need a second pass, walking through the tokenized
Applesoft program and looking for problems.  If somebody wants to write
that in C/C++ and give it a BSD-ish license or donate it to the public
domain, I'll tuck it into CiderPress.
