public pure subroutine hexToInt128(input, output, error, startpos, endpos)Parse the input string as bits represented by hexadecimal digits to an int128 value.
This subroutine ignores leading and trailing whitespaces.
This subroutine considers an error to has occurred:
1. If the input string only contains empty spaces.
2. If the input string have a length of zero.
3. If the value for either the startpos or endpos arguments is incorrect.
4. If the input string contains a value that is beyond the capacity of the int128 data type.
5. If the input string is not a valid hexadecimal string.
