QEdit

QEdit was an MS-DOS text editor requiring 50 KB of memory. SemWare-Qedit-BoxManualAndDisk

QEdit stored all of the files being edited in RAM. Later versions of QEdit added support for the various systems of memory supported by MS-DOS:

, up to a maximum of 16 MB. QEdit was ported to

initially as a 16-bit application for Microsoft's OS/2 1.x. This 16-bit OS/2 version of QEdit had version 1.x. Version 1.50 for 16-bit OS/2 is dated February 1990. SemWare ported QEdit for 32-bit OS/2 with the release of QEdit Pro 3.0 for OS/2 in February 1994 which sold for $99. Version 3.0 included multi-file operation, HPFS support and access to the OS/2 Clipboard. SemWare claimed "over 120,000 licensed users" on all platforms at that time. The last version released for OS/2 was "TSE Junior/2" v4.00e released in February 1997. It was functionally equivalent to TSE Junior v4.00e with support for OS/2's system-wide clipboard and long filenames. It retailed at the time for $99 and was supplied with a copy of the MS-DOS basic version.

The SemWare Editor (TSE)

QEdit was rewritten and significantly expanded, and eventually released as The SemWare Editor (TSE) 1.0. The initial release maintained the tradition of fast I/O and response, fast search, a simple text scripting language and the fundamental design of a native core with functionality split between native code and scripting. New TSE features included a more powerful scripting language (SAL),

s, a native Win32 port, SAL access to Win32 DLL entry points, a 'graphical' port using the native Windows GDI (previous versions employed the console window), optional native dialogs (e.g. Open), and graphical features such as window transparency.

s support creation of arbitrary buffers, including non-interactive buffers not visible to the user. Many functions are available to access and manipulate buffers and their contents, effectively acting as very large text containers.
