public pure subroutine hexToInt128TrueError(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.
Error codes:
0 - none
1 - empty strings
2 - invalid format
3 - value too large for data type
5 - Invalid argument endpos/startpos
Note
