h3	#define	

pre	#define <name> <value>

p	Define an alias for a well-known pseudo instruction or define a global label.

p	#define is used in some sources in three ways:

ol
li	Define an alias for an instruction name
li	Define a label
li	Define a preprocessor function with arguments

p	From that the most common aliases and the definition of labels are supported.

h5	Define an alias

pre	#define equ  .equ
	#define	defs .ds

p	Within the following groups names can be mapped in any direction:

ul
li	org .org
li	defw dw .dw .word
li	defb db .db .byte
li	defm dm .dm .text .ascii
li	defs ds .ds .block

p	All these mappings are recognized and … ignored.
p	Other mappings result in an error. (if you feel a mapping should be added then send an email.)
	zxsp does not support aliases for instruction names, but it already knows about quite a lot of them. Therefore it can ignore these #defines.

p	Use of this directive is discouraged. It is provided because some sources use it. Just delete it.

	
h5	Define a global label

pre	#define	foo	123
	#define bar $ - shelf

p	#define can be used to define a global label as with

pre	foo:: equ 123
	bar:: equ $ - shelf

p	Labels defined with '#define' are always global, even if defined inside a local context.

p	Use of this directive is discouraged, many assemblers do not understand it. Use the pseudo instruction 'equ' instead.
