MID$
(Function)
Extracts a character string for the designated number of characters from a character string.
MID$ (<character string >, <Start position>[, <Number of digits>])
This statement extracts a character string for <Number of digits> from <Start position> of <Character string>.
If the character string includes a NULL value, the NULL value is returned.
If a value longer than the character string is designated in <Number of digits>, the whole character string is returned.
If <Number of digits> is ignored, or if the character string has fewer characters than the number of digits designated, all characters after the start position are returned.
If a value longer than the character string is designated in <Start position>, the whole character string is returned.
<Number of digits> is handled as byte counts.
