Purpose: explain the proper use of source and other means of including user function code into a running interpreter (wishrc/tclshrc/whatever--see "[The RC File]" for details). Also provide a launching point for discussions on send, use of socket based communications like the comm extension, and other alternatives. ---- * Tcl's [source] command * Tcl's [socket] command * The comm package [http://www.schooner.com/~loverso/tcl-tk/#comm]. ''comm now appears to be part of [TclLib]. --[WHD]'' * Tk's [send] command * Tcl's [dde] command. This is windows specific. ---- See also [How to change a running system] - RS - This page demonstrates how long titles in the Wiki can be. Still, shorter titles might draw more links from other pages - it's just lazyness... ''Please choose more succinct page titles...'' <> Example
