Some of Tcl's documentation refers to ''procedure''s
as a distinct type of command.

A ''procedure'' is a Tcl command that is created
by the [proc] command.

For example the [info args] command expects its
argument to be the name of a procedure.  Names 
of other commands passed to [info args] will
cause an error to be raised.

[ZB] 26.06.2008. - in fact, technically, there aren't '''any''' procedures at all in TCL, because returning a value by TCL's "proc-s" is obligatory. So in TCL, there are only functions available (a procedure is just a block of commands, to perform specific task; one can say: "a function, which doesn't return any value" - like f.e. "void" in C - see Pascal as well).
