sms/vdp: clear rest of line on line feed This allows us (in the following commit), to stop unvariably spitting 64 chars by line in LIST. This way, short lines don't use 3 rows per line (the line number uses 3 chars, which brings us to 67 chars per line). If we don't do that, we end up with the old contents of the line being kept at the right of the printed line. 2020-11-08 16:43:37 -05:00			`( bit 6, enable display, bit 7, ?? ) 0x81c0 _ctl ;`
Adjust Grid subsystem Rename ROWS to LINES (it's what VE uses). Also, don't use COLS and LINES as immediates in the Grid subsystem: we expect those words to be available at runtime. 2020-11-10 19:06:39 -05:00
