A program was written in GFA-BASIC for the Atari ST microcomputer aimed at drawing two-dimensional homology dotplot patterns for two protein or DNA sequences. The program, built around a machine-code subroutine, communicates interactively with the user by means of a multi-button dialogue panel and mouse-directed input. A 1000 x 1000 sequence comparison with a 14: 21 stringency window takes 12 s.
