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.
