MID ​

Returns a part of a text.

Positions start at 0. Near the end you get fewer characters. A start behind the end gives an empty text. A negative start or length raises INVALID_ARGUMENT.

Parameters and results

• text STRING: the text
• start INTEGER: the position of the first character
• length INTEGER: the number of characters (optional, default the rest of the text)
• result result STRING: the part of the text

    PARAMETER text name ;
    PARAMETER start 2 ;
    PARAMETER length 3 ;
    RESULT result part
