RE: Accessing 'C' variables from assembly:

The approach suggested is unnecessary, you can use the '[' ']' notation (see
the TCX users manual), to "symbolically" get access to the local stackframe
offset of a local variable or parameter in all versions of Logical Systems "C"
from 88.4 on.  For a "global" variable, just listing the name (as in the
example), will work.

Although the bracket notation may always be replaced by a programmer computed
offset (counting up the local variables, etc.), its use is STRONGLY encouraged
since newer versions of TCX include some optimizations which make programmer
determination difficult (and version dependent).
