Write&Set, according to its author, is a full-featured word processing program with hyphenation, contents creation, footnotes, index, embedding graphics and a lot of more. It is an alternative concept of word processing for people who don't like Winword-like programs. Shareware."
This leaves out the most important aspect of the appeal it has for some. It is a program that emulates WordStar. One of the things that makes it different from Wordstar is that editing and formatting are done in separate programs, called WSedit and WSformat respectively. The first is freeware, the second shareware.
The programs work thus very much like Tex, which itself seems to have its roots in Unix, where once upon a time text was written in vi and then formatted for printing with nroff.
"Write&Set uses the Wordstar 4.0 file format. Write&Set also reads Wordstar 5-7 files, but always saves Wordstar 4 format. (The Wordstar 4 file format does not use the 'symmetrical sequences' of Wordstar 5-7.)"
I played with WSedit and found it very interesting. Its way of formatting reminds me very much of lightweight markup languages or a wiki format like ConnectedText. Since it really does not provide any functionality that would go beyond such markup languages, I would not go back to it, however.
While I remembered some of the CTRL-commands, I had completely forgotten about the block and dot commands.
