.SH NAME

lappend \- Append list elements onto a variable

.SH SYNOPSIS

\fBlappend \fIvarName \fR?\fIvalue value value ...\fR?

.BE

.SH DESCRIPTION

.PP

This command treats the variable given by \fIvarName\fR as a list

and appends each of the \fIvalue\fR arguments to that list as a separate

element, with spaces between elements.

If \fIvarName\fR doesn't exist, it is created as a list with elements

given by the \fIvalue\fR arguments.

\fBLappend\fR is similar to \fBappend\fR except that the \fIvalue\fRs

are appended as list elements rather than raw text.

This command provides a relatively efficient way to build up

large lists.  For example, ``\fBlappend a $b\fR'' is much

more efficient than ``\fBset a [concat $a [list $b]]\fR'' when

\fB$a\fR is long.
