The editor has been written with great attention being placed on the usercomputer interface to make it particularly userfriendly. It is written in C++ for use under Windows on a PC. The basic operations are controlled by the mouse. The editor provides 109 basic symbols partitioned into 10 menus. Symbols on a score can be deleted, copied, or altered, and the score scrolled up or down. Scores can be created, stored, retrieved for further editing, and written out as PostScript files for printing.
