The limit of 8 characters for variable names are for 'internal' variables.
The ones that are NOT global and defined within local proceedures.
It is the external (globbal) variables that have additional characters added
to form the external symbol.  Therefore, external variables usually have
a limit less than 8.  I don't remember how much but I think that it varies
among different releases of the compiler.
