The alignment of homologous sequences with each other and their display has proved adifficult task, despite a frequent requirement for this process. HOMED enables related sequences to be edited and listed in parallel with each other. The editor function uses a full screen editor which emulates the text editors KED and EDT (on PDP11 and VAX11 respectively) and which can be adapted to emulate other text editors. This emulation has been adopted to simplify user learning of editing functions. HOMED provides functions for listing the sequences in a variety of formats and for generating a consensus sequence as well as providing a series of tools for maintenance of the sequence database. HOMED has been implemented in Pascal in a modular fashion to enhance portability.
