jot
Synopsis:
$jot(
Technical:
This script is used to obtain a series of integers, from the first input to
the second. Negative numbers are permitted, and the series may be ascending
or descending.
Practical:
This function is used to generate a number range. One popular use for this is
in conjunction with $chr(), allowing a range of ascii characters to be
returned (which then might be stripped from another string, etc.).
Returns:
* number range from start to stop
* if less than 2 arguments, empty string
* if more than 2 arguments, first argument
* if non-digits entered, 0 (zero)
Examples:
$jot(2 6) returns "2 3 4 5 6"
$jot(3 -2) returns "3 2 1 0 -1 -2"
$jot(4) returns "" (empty string)
$jot(4 6 8) returns "4"
$jot(a 4) returns "0"
