and other popular programmer editors of the time which implemented a native engine or core, with the bulk of the program implemented via their scripting languages.
Some of Qedit's speed was due to memory-based editing – the editor and all buffers and workspace required physical memory. Later versions of Qedit added support for the various systems of memory supported by MS-DOS: expanded memory

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 . By that date the "read me" file included with the software claimed "90,000 licensed users of QEdit products, worldwide" -all platforms-.
After IBM and Microsoft had parted ways, IBM released the first 32-bit version of OS/2: v2.0 in March 1992. Semware ported QEdit for 32-bit OS/2 with the release of Qedit Pro 3.0 for OS/2, released on February, 1994 and sold for $99. Version 3.0 for 32-bit OS/2 included multi-file operation, HPFS support, and access to the OS/2 Clipboard. Semware claimed by that time "Over 120,000 licensed users" on all platforms.
The last version released for IBM's OS/2 was "TSE Junior/2" v4.00e released on February, 1997, functionally equivalent to TSE Junior v4.00e for DOS, with the addition of access to the system-wide OS/2 clipboard, and HPFS (long filenames) support. It retailed at the time for $99 and was supplied with a copy of the DOS basic version .
The SemWare Editor (TSE)
Qedit was rewritten and greatly expanded, ultimately released as The SemWare Editor (TSE) 1.0. The initial release, like Qedit, had 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 script.
TSE features not in Qedit included a new, more powerful scripting language (SAL), regular expression

TSE has at times been referred to as 'Tessie', derived from its acronym (TSE).
TSE used the codename 'RoadRunner' during initial development, until it was formally named TSE. Comments from Sammy Mitchell indicated the name change was forced due to a trademark dispute raised by another business.

, fractional lines/columns and so forth.
The transition to a 'graphical' implementation brought several advantages by being a graphical application not tied to a Windows 'console', including a broader selection of fonts, native dialogs for Open, Save and Print (the text-mode prompts remain available via configuration option) and window resizing.
Qedit and TSE supported various screen modes (different numbers of columns and rows, e.g., 80 × 25) based on the underlying video display options; with the graphical version windows could be sized to any number of rows and columns. This occurred around the same time larger displays were becoming increasingly common.
