Removed (pretty inconsistently used) tab chars from source code base. 2013-05-09 11:56:54 +00:00			`.export _chlinexy, _chline`
Introduced internal gotoxy that pops both parameters. About all CONIO functions offering a <...>xy variant call popa _gotoxy By providing an internal gotoxy variant that starts with a popa all those CONIO function can be shortened by 3 bytes. As soon as program calls more than one CONIO function this means an overall code size reduction. 2016-06-05 12:58:38 +00:00			`.import gotoxy, cputdirect`
Allow to override chars used for horizontal and vertical lines. 2015-10-12 19:04:06 +00:00			`.importzp tmp1, chlinechar`
