- .SH NAME
- lappend \- Append list elements onto a variable
- .SH SYNOPSIS
- \fBlappend \fIvarName value \fR?\fIvalue 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.
