public function decToInt64(input, output, startpos, endpos) result(error)Parse the input string as a signed decimal integer string to an int64 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 smaller than the min value of the int64 data type or larger then the max value of the int64 data type.
5. If the input string is not a valid signed decimal integer string.
