FOCAL, 5/69
FOCAL8-52

Edward A. Taft, 111, Manchester, Massachusetts

This is a new version of FOCAL, based on FOCAL W, 8/69,
which has been expanded and rewritten to remove numerous
bugs and restrictions and to provide a large number of new
commands and extended capabilities. Some of the new
features are:

l) Better control over I/O devices, including high speed
punch; 2) New I/O formats, including buffered input that
accepts expressions as well as numbers, input and output of
single ASCII characters, and a tabulation controller; 3) A
group of "OPTION" commands that perform minor functions
such as suppressing or restoring keyboard echo and changing
I/O modes; 4) A more compact extended function package,
resulting in an enlarged user area; also a command for de-
leting the extended functions; 5) Extended command formats,
also a provision for using calculated line numbers.
