- .SH NAME
- append \- Append to variable
- .SH SYNOPSIS
- \fBappend \fIvarName value \fR?\fIvalue value ...\fR?
- .BE
-
- .SH DESCRIPTION
- .PP
- Append all of the \fIvalue\fR arguments to the current value
- of variable \fIvarName\fR. 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.
