This function returns a string that is based on text a, but has been reduced to length b. The result text is created from the text beginning with the rightmost number (not digit!), concatenated with the text beginning at the far left (until the concatenated text has reached the maximum length). If the right part is already longer than the maximum length, it is shortened from the right to the appropriate length. See examples.

Parameters

Parameter	Description
a	Text.
b	Length.

Very very long streetname 127 b	2	12 ( Note: The rescued text 127 b has been shortened to length 2 from the right. )
