set(TCL)


set -- read and write variables

Synopsis

set varName [value]

Description

Returns the value of variable varName. If value is specified, then it sets the value of varName to value, creating a new variable if one doesn't already exist, and returns its value. If varName contains an open parenthesis and ends with a close parenthesis, then it refers to an array element: the characters before the first open parenthesis are the name of the array, and the characters between the parentheses are the index within the array. Otherwise varName refers to a scalar variable. If no procedure is active, then varName refers to a global variable. If a procedure is active, then varName refers to a parameter or local variable of the procedure unless the global command has been invoked to declare varName to be global.
