ZDE 1.6 (Z-System Display Editor) reconstituted source - MECPARTS

11/19/2020

Using the source code of [VDE 2.67] (http://www.classiccmp.org/cpmarchives/cpm/Software/WalnutCD/enterprs/cpm/utils/s/vde267sc.lbr) as a guide, I've reconstituted the source code for ZDE 1.6.

The source has been assembled with:

• Al Hawley's ZMAC: assemble as is.
• MicroSoft's M80: rename to ZDE16.MAC, un-comment the first two lines and assemble. Use RELHEX to create ZDE16.HEX.
• ZASM (Cromemco's ASMB): Rename to ZDE16.Z80 and assemble. Use RELHEX to create ZDE16.HEX.

Use MLOAD to create ZDE16.COM.

There are still a couple of routines new to ZDE that I haven't figured out (yet). But most of them have been sussed out.

ZDE 1.7 - MECPARTS 11/24/2020

I've fixed the "doesn't preserve timestamps for files larger than a single extent under ZSDOS" bug that was present in v1.6. The existing ZDENST16.COM program will work with the 1.7 to set the program up for your terminal and printer.

ZDE 1.8 - Lars Nelson 12/3/2022

Added routine to save create time stamp under CP/M Plus since CP/M Plus, unlike ZSDOS, has no native ability to set time stamps.

ZDE 1.9 - Peter Onion 03/27/2025

• Added support for ANSI PgUp, PgDn, Home, & End.
• Support ANSI F1 key for menu/error escape.
