; Compiler zero-page configuration file
;
; Each of the following items must be defined with the exception of
; the 'Float' item if no floating point is used. The User Reg space
; can be of any desired size. This space is used by the compiler to
; hold automatic variables that would normally be located on the
; pseudo-stack. Priority is especially given to pointers.
;
; NOTE! Any changes made to this file must be reflected in the
; WDC02CC.CFG file in the BIN directory and then the libraries
; MUST be rebuilt. Also any files previously compiled MUST be
; recompiled.
