EPSON PRINTER TIP When using the printer to print your Macro Assembler .LST files, put the following line at the beginning of your .ASM files to automatically switch the printer to 132 column mode: PAGE ,132 ;^O That's a Control-O -seen by the printer but ignored by the assembler. To automatically revert to 80-column mode at the end of the listing, append a comment with a Control-R to the last line in your listing: ....;^R USING RADIX 16 If you use .RADIX 16 to avoid typing in H's after all your hex numbers, it won't work for hex 0B or 0D. This is because the assembler will always interpret them as meaning the no. is Binary (B) or Decimal (D) - unless they are followed by an H, i.e. 0BH. Thanks to Boca Raton for these tips. JW
