set -- read and write variables
Synopsis
set
varName
[
value
]
Description
Returns the value of variable
varName
. If
value
is specified, then it
set
s 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.
