WordStar V3.30 for the Gemini IVC/SVC

by D.W. Birch

This article details the changes necessary to support the keyboard cursor keys for WordStar version 3.30. All other functions i.e. clear to end of line/​screen can be patched through the instal program (called WINSTALL). See article in 80-BUS NEWS Vol. 2 issue 3 page 11 for Installation of WordStar V2.2 on IVC by Richard Beal.

New addresses are necessary for Ver. 3.30 as the patch area has been changed. Below are detailed the changes for support of the cursor keys and also a few other locations that users may find useful to patch. Patching can be done either with DDT/ZDT etc. or better via the patcher in WINSTALL (accessed via a “+” at the main install menu).

Terminal Exit1A 1B 73 43 0A 1B 4D

I found this very useful as the clock display if selected under WordStar does get in the way.
