.SH NAME
|
|
lrange \- Return one or more adjacent elements from a list
|
|
.SH SYNOPSIS
|
|
\fBlrange \fIlist first last
|
|
.BE
|
|
|
|
.SH DESCRIPTION
|
|
.PP
|
|
\fIList\fR must be a valid Tcl list. This command will
|
|
return a new list consisting of elements
|
|
\fIfirst\fR through \fIlast\fR, inclusive.
|
|
\fILast\fR may be \fBend\fR (or any
|
|
abbreviation of it) to refer to the last element of the list.
|
|
If \fIfirst\fR is less than zero, it is treated as if it were zero.
|
|
If \fIlast\fR is greater than or equal to the number of elements
|
|
in the list, then it is treated as if it were \fBend\fR.
|
|
If \fIfirst\fR is greater than \fIlast\fR then an empty string
|
|
is returned.
|
|
Note: ``\fBlrange \fIlist first first\fR'' does not always produce the
|
|
same result as ``\fBlindex \fIlist first\fR'' (although it often does
|
|
for simple fields that aren't enclosed in braces); it does, however,
|
|
produce exactly the same results as ``\fBlist [lindex \fIlist first\fB]\fR''
