- .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.
- .VS
- \fIFirst\fR or \fIlast\fR
- .VE
- 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''
