If varName doesn't exist, it is given a value equal to the concatenation of all the value arguments. This command provides an efficient way to build up long variables incrementally. For example, ``append a $b'' is much more efficient than ``set a $a$b'' if $a is long. SEE ALSOconcat(n), lappend(n)KEYWORDSappend, variable
