Built-In Commands - append manual page

### NAME

append - Append to variable

### SYNOPSIS

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.

### KEYWORDS
