set
set(n) Tcl Built-In Commands set(n)
__________________________________________________________________________________________________________________________________________________NAME
set - Read and write variables
SYNOPSIS
set varName ?value?
_________________________________________________________________DESCRIPTION
Returns the value of variable varName. If value is specified, then set the value of varName to value, creating a new variable if one does
not 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 varName includes namespace qualifiers (in the array name if it refers to an array element), or if varName is unqualified (does not
include the names of any containing namespaces) but no procedure is active, varName refers to a namespace variable resolved according to
the rules described under NAME RESOLUTION in the namespace manual page.
If a procedure is active and varName is unqualified, then varName refers to a parameter or local variable of the procedure, unless varName
was declared to resolve differently through one of the global, variable or upvar commands.
EXAMPLES
Store a random number in the variable r:
set r [expr {rand()}]
Store a short message in an array element:
set anAry(msg) "Hello, World!"
Store a short message in an array element specified by a variable:
set elemName "msg"
set anAry($elemName) "Hello, World!"
Copy a value into the variable out from a variable whose name is stored in the vbl (note that it is often easier to use arrays in practice
instead of doing double-dereferencing):
set in0 "small random"
set in1 "large random"
set vbl in[expr {rand() >= 0.5}]
set out [set $vbl]
