This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

Shortened interactive commands

In Tcl, if you're working in interactive mode you can abbreviate the commands you type in, as long as your commands remain unique. So instead of puts you can write put or even pu ... but if you try to run just the p command you'll get

% p hello
ambiguous command name "p": package pid proc puts pwd
%


If you're running from a a file of Tcl commands, though, you need to specify the command name in full - puts.
