append

Append to variable 

Tclsh Built-In Commands


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.
