There are 3 problems:

1.) strINPUT is too small, since the string must be terminated
with a null char
2.) You have not defined a function Split()
3.) strGLL is an array variable. Since Serial_Read(0)
gives back one character, you must write strGLL(i) = Serial_Read(0)

It looks like that you should consult the demo programs first, to get
some impression how to work with the BASIC.

Peter
