Ace Microsystems Ltd, Brentford, Middlesex has added Lex-Manager, a time and resource management system, to its Lex word processing and database package: the new module is written in Filetab-D and presently runs on MS-DOS micros and DEC VAX and PDP-11 machines; a Unix version of the menu-driven program, which enables scheduling of meetings for groups of people, is also planned.
