- ; 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
- ;........................................................................
- ;
- ; Put the following code in your program (a .LIB won't work)
- ;........................................................................
- ;
- ; 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 ; /

- ; DEMO of it's use.
