; 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.
