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 scr ipt file via the TEX command CALL <filename>.



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.-TEX was a subsystem of Honeywell TSS.
