again (using the context_save command extension).

Arguments
ctxt
var
index_if_array
The index_if_array argument is ignored when the var argument is a scalar variable.
Note
If var is unspecified, retrieves the whole variable table saved in the context.
If var is specified and index_if_array is not specified, or if index_if_array is specified but var is a scalar
variable, retrieves the value of var.
If var is specified, and index_if_array is specified, and var is an array variable, retrieves the value of the
specified array element.
Result String
Resets the Tcl global variables to the state that they were in when the save was performed.
