Drawing lines: TABLE (6502SP version)

Name: TABLE [View in context] Type: Variable Category: Drawing lines Summary: The line buffer for line data transmited from the parasite
Lines are drawn by sending the line coordinates one byte at a time from the parasite, using the OSWRCH 129 and 130 commands. As they are sent, they are stored in the TABLE buffer, until all the points have been received, at which point the line is drawn. LINTAB points to the offset of the first free byte within TABLE, so the table can be reset by setting LINTAB to 0.
