For example, +.QW "\fBlappend a $b\fR" +is much more efficient than +.QW "\fBset a [concat $a [list $b]]\fR" +when \fB$a\fR is long. +.SH EXAMPLE +.PP +Using \fBlappend\fR to build up a list of numbers. +.PP +.CS +% set var 1 +1 +% \fBlappend\fR var 2 +1 2 +% \fBlappend\fR var 3 4 5 +1 2 3 4 5 +.CE +.SH "SEE ALSO" +list(n), lindex(n), linsert(n), llength(n), lset(n), +lsort(n), lrange(n) +.SH KEYWORDS +append, element, list, variable |
