The FRED Text Editor FRED is a line editor descended from the QED editor. It allows all the usual interactive editing operations: creating, deleting, modifying and saving text, global substitutions, and the like. In addition, it can be used to write sophisticated text manipulation programs. Our current library of stored FRED programs includes programs to play tic-tac-toe, to convert RUNOFF source into source for our TF text formatter, to generate and run an EXEC file to copy a catalog, and so on.

Some of the features that distinguish FRED from other editors are:

The ability to "undo" up to 10 lines of commands, if you make a mistake or change your mind.
Multiple buffers (workspaces) to let you work on more than one file at once, or move text about from one location in a file to another.
The ability to "capture" output from a FRED or TSS command, and place that output in a buffer for editing.
A sophisticated pattern matcher, allowing you to locate strings and perform various manipulations on them.
Simple commands for upper or lower casing text.
Control structures, including loops and GOTOs.
The ability to put comments in FRED programs.

FRED comes complete with a reference manual, a tutorial for beginners, and a more advanced guide to writing FRED programs. There is also a small library of utility programs. FRED operates in TSS or batch.
