public function hexToInt32(input, output, startpos, endpos) result(error)Parse the input string as bits represented by hexadecimal digits to an int32 value.
This function ignores leading and trailing whitespaces.
This function return a logical value of .TRUE. if an error has occurred during parsing, or .FALSE., otherwise.
This function 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 int32 data type.
5. If the input string is not a valid hexadecimal string.
