EQU (Equate Symbol)
The EQU directive assigns the value of a constant expression to a symbol. The
assembler treats subsequent occurrences of the symbol as the value of the
constant expression.
Syntax:
The EQU directive requires a label and a constant expression argument.
label EQU const_expr
Example:
The following example loads TOS with the content of the general-purpose
register R0 (base page offset value 8), using the mnemonic name “R0”:
R0 EQU 8
Example APEXP ; ( -- r0)
push !R0 ; ( r0 )
ret ; return to caller
