[HP48/49] Command Line Parsing

[Bruno]

Hi,

I'm trying to improve the parsing routines of HPDL using the GetNextToken entry,
and I don't understand how it work, especially on the content of the hxs mask that it expect to find on the stack.

I think each one of the 256 nibbles represent a set of parsing rules to apply to the corresponding ASCII character,
but If I'm right, what is the meaning of each bit ?

Thank you for your help.
