A function that can be used in Formulas.
truncateLeft$ (string$, maximumNewWidth)
string$ until the result is at least as short as maximumNewWidth: assert truncateLeft$ ("hello", 3) = "llo"
assert truncateLeft$ ("hello", 5) = "hello"
No padding takes place, so the resulting string may be shorter than maximumNewWidth:
assert truncateLeft$ ("hello", 12) = "hello"
Note that maximumNewWidth cannot be negative:
asserterror Can never truncate a string down to -3 characters.
a$ = truncateLeft$ ("hello", -3)
