| + | ======Synopsis:====== | ||
| + | $__jot__(<start> <stop> <interval>) | ||
| + | |||
| + | ======Technical:====== | ||
| + | * If the <start> argument is omitted the empty string is returned. | ||
| + | * If the <stop> argument is omitted the empty string is returned. | ||
| + | * If the <interval> argument is omitted the default value of 1 is used. | ||
| + | * If the <interval> argument is 0, the empty string is returned. | ||
| + | * The <interval> argument should be an integer value -- support for fractional numbers will be added in the future. | ||
| + | * The <interval> argument should be positive; but if you specify a negative value, the absolute value of <interval> will be used. | ||
| + | * If <start> is less than <stop>, then consider the sequence \\ [<start>, <start>+<interval>, <start>+<interval>+<interval>, ... <L>], where <L> is less than or equal to <stop>. | ||
| + | * If <start> is greater than <stop>, then consider the sequence \\ [<start>, <start>-<interval>, <start>-<interval>-<interval>, ... <L>], where <L> is greater than or equal to <stop>. | ||
| + | * This function returns a list of words that correspond to the elements in the smallest sequence that models the appropriate sequence. | ||
| + | |||
| + | ======Practical:====== | ||
| + | This function creates a list of all of the numbers between <start> and <stop>, | ||
| + | with a step of <interval>. Ranges can be ascending or descending, depending on | ||
| + | whether <stop> is greater than or less than <start>. You can iterate over the | ||
| + | return value with [[FE]] or [[FOR]] i IN. Another popular use is to pass the | ||
| + | return value to $[[chr]]() to create a range of ascii characters. | ||
| + | |||
| + | ======Returns:====== | ||
| + | Every <interval>th number between <start> and <stop>, inclusive. | ||
| + | |||
| + | ======Examples:====== | ||
| + | <file> | ||
| + | $jot(2 6) returns "2 3 4 5 6" | ||
| + | $jot(2 7 2) returns "2 4 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" | ||
| + | </file> | ||
