.SH NAME
lset \- Change an element in a list
.SH SYNOPSIS
! \fBlset \fIlist ?index...? newValue\fR
.BE
.SH DESCRIPTION
.PP
! The \fBlset\fP command accepts a parameter, \fIlist\fP, which
it interprets as the name of a variable containing a Tcl list.
It also accepts zero or more \fIindices\fP into
the list. The indices may be presented either consecutively on the
command line, or grouped in a
Tcl list and presented as a single argument.
! Finally, it accepts a new value for an element of \fIlist\fP.
.PP
If no indices are presented, the command takes the form:
.CS
! lset list newValue
.CE
or
.CS
! lset list {} newValue
.CE
! In this case, \fInewValue\fP replaces the old value of the variable \fIlist\fP
.
.PP
When presented with a single index, the \fBlset\fR command
! treats the content of the \fIlist\fR variable as a Tcl list.
It addresses the \fIindex\fR'th element in it
(0 refers to the first element of the list).
When interpreting the list, \fBlset\fR observes the same rules

The command constructs a new list in which the designated element is
