;	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.
