- append varName value ?value value ...?
-
-
- DESCRIPTION
- Append all of the value arguments to the current value of
- variable varName. 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.
