NAME    [Toc]    [Back]

     set - Read	and write variables

SYNOPSIS    [Toc]    [Back]

     set varName ?value?

DESCRIPTION    [Toc]    [Back]

     Returns the value of variable varName.  If	value is specified, then set
     the value of varName to value, creating a new variable if one doesn't
     already exist, and	return 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.
