Print Blank To

One of the problems using Pprint and variable width fonts highlighted itself when I wrote a menuing system, I needed to over write what was a line already. Normally I would just count up the spaces needed and add them to the string being printed i.e. 10 characters from the 16 places needing to be overwritten, that’s 6 spaces added to the end.

Variable width fonts are as it says, variable in width. The Letter “i” is smaller that “W”, now you could count up the number of pixels in each character and then add enough spaces at the end to make up the difference. Spaces though are only 2 pixels wide; to make up the 6 normal spaces required would require 18 variable width spaces. It was to solve this problem I wrote “PBT.INC”

The PRINT_BLNK_TO macro enables you to define an end point on the currently printed line and print blank spaces to it.

Syntax: PRINT_BLNK_TO Variable - Variable can be a constant, variable, or expression
