Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
lrange - Return one or more adjacent elements from a list
SYNOPSIS
lrange list first last _________________________________________________________________
DESCRIPTION
List must be a valid Tcl list. This command will return a new list consisting of elements first through last, inclusive. First or last may be end (or any abbreviation of it) to refer to the last element of the list. If first is less than zero, it is treated as if it were zero. If last is greater than or equal to the number of elements in the list, then it is treated as if it were end. If first is greater than last then an empty string is returned. Note: ``lrange list first first'' does not always produce the same result as ``lindex list first'' (although it often does for simple fields that aren't enclosed in braces); it does, however, produce exactly the same results as ``list [lindex list first]''
EXAMPLES
Selecting the first two elements: % lrange {a b c d e} 0 1 a b Selecting the last three elements: % lrange {a b c d e} end-2 end c d e Selecting everything except the first and last element: % lrange {a b c d e} 1 end-1 b c d Selecting a single element with lrange is not the same as doing so with lindex: % set var {some {elements to} select} some {elements to} select % lindex $var 1 elements to % lrange $var 1 1 {elements to}
