unset(n) Tcl Built-In Commands unset(n)_________________________________________________________________NAMEunset - Delete variables
SYNOPSISunset name ?name name ...?
_________________________________________________________________DESCRIPTION
This command removes one or more variables. Each name is
a variable name, specified in any of the ways acceptable
to the set command. If a name refers to an element of an
array then that element is removed without affecting the
rest of the array. If a name consists of an array name
with no parenthesized index, then the entire array is
deleted. The unset command returns an empty string as
result. An error occurs if any of the variables doesn't
exist, and any variables after the non-existent one are
not deleted.
