Z System Display Editor, version 1.6. A small, fast, powerful WordStar-type text editor for all CP/M and compatible systems with the Z80 processor. In some ways superior to its big brother VDE, this version of ZDE adds fully functional Auto-Indent capabilities, Proportional Formatting, Auto-Recall of last response to prompts, Global Find/Replace, Return to Previous Position (^QP) and more to what many felt was already the best editor available for CP/M.
