This command will +return a new list consisting of elements +\fIfirst\fR through \fIlast\fR, inclusive. +\fIFirst\fR or \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'' + +.SH KEYWORDS +element, list, range, sublist |
