That's pretty well what I'm working on. What you ahve to do is
define all your strings (in the newtypes) as String1.b followed
immediately by Pad1.b[n] where 'n' is the maximum length of the
string. then you can use
poke.s &thing\String1,Left$(AString$,n)
to copy a string into the newtype and
AnotherString$ = peek$(&thing\String)
to extract it back to a string. You need one more byte than the
string length to hold the terminating $00 byte.
You can compare a real string with a newtype string (or two newtype
strings) using (Guess who...) David's AsmStrCmp routines.
Give me a yell offline if you need more help.
Cheers
