In 1979, Honeywell Information Systems announced a new programming language for their time-sharing service named TEX, an acronym for the Text Executive processor. TEX was a first generation scripting language, developed around the time of AWK and used by Honeywell initially as an in-house system test automation tool. TEX extended the Honeywell Time-Sharing service (TSS) line editor with programmable capabilities which allowed the user greater latitude in developing ease-of-use editing extensions as well as write scripts to automate many other time-sharing tasks formerly done by more complex TSS FORTRAN programs. ==Overview== TEX was a subsystem of Honeywell TSS. Users would enter the TSS command 'tex' to change to a TEX session mode of operation. TEX expressions could be entered directly on the command line or run from script file via the TEX command CALL TEX programs are a collection of TSS line editing commands, TSS session commands and TEX statements. TEX variables could be inserted into TSS commands and TSS line editor commands via the TEX variable substitution feature. TEX programs were primarily designed to extend the line editor system. Consequently, TEX had no concept of file input/output relying instead on applying line edit commands to the working file and saving as needed. The key developers of TEX at Honeywell were Eric Clamons and Richard Keys with Robert Bemer, famous as the father of ASCII and grandfather of COBOL, acting in an advisory capacity.〔''Introduction to TEX'', p.144 Interface Age - Aug 1978〕 TEX should not be confused with TeX a typesetting markup language invented by Donald Knuth. The American Mathematical Society has also claimed a trademark for TeX, which was rejected, because at the time this was tried (early 1980s), “TEX” (all caps) was registered by Honeywell for the “Text EXecutive” text processing system.〔 * Donald E.
