If \fIvarName\fR doesn't exist, +it is given a value equal to the concatenation of all the +\fIvalue\fR arguments. +This command provides an efficient way to build up long +variables incrementally. +For example, ``\fBappend a $b\fR'' is much more efficient than +``\fBset a $a$b\fR'' if \fB$a\fR is long. + +.SH KEYWORDS +append, variable |
