public pure subroutine decToInt64(input, output, error, startpos, endpos)Parse the input string as a signed decimal integer string to an int64 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 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.
