; PRTVAL.Z80 version 2.0 Jim Lill 17 Jan 88
;
; PRTVAL uses a method referred to in M80 manuals for printing values
; during assembly. My earlier version required ' .RADIX n' to control
; format of the printed value. Adding a second macro solved that and
; I've eliminated the use of the '%' in each call. This means math
; must be done with EQU prior to the PRTVAL call. I find this acceptable
; as it helps maintain readability.
;
; SYNTAX:
;
; PRTVAL RADIX,<MESSAGE1>,VALUE,<MESSAGE2>
; | | | |
; | | | |___ 'trailing' message
; | | |___ value to be printed (no math here!)
; | |___ 'leading' message
; |___ radix of printed value 2, 10, 16

;
; PRTVAL macro(s) prints text and value during assembly
;
prtval2 macro m1,v1,m2 ; \
.printx m1 v1 m2 ; +- this is the print value macro
endm ; /
prtval macro r,msg1,val,msg2 ; \
.radix r ; passing the radix value
prtval2 <msg1>,%val,<msg2> ; requires the uses of 2 macros
endm ; /
