RE: [U2] Deep and long indentations vs multiple exit points

[Keith Johnson (DSLWN)]

Dave Barret gave this code as an example:

        GOSUB OPERATION.1
        IF (NOT(ERROR)) THEN
          GOSUB OPERATION.2
          IF (NOT(ERROR)) THEN
            GOSUB OPERATION.3
            IF (NOT(ERROR)) THEN
              GOSUB OPEARTION.4
            END
          END
        END

What about this version?

        GOSUB OPERATION.1
        IF ERROR ELSE GOSUB OPERATION.2
        IF ERROR ELSE GOSUB OPERATION.4
        IF ERROR ELSE GOSUB OPERATION.5

or, more acceptably:

        GOSUB OPERATION.1
        IF GOOD THEN GOSUB OPERATION.2
        IF GOOD THEN GOSUB OPERATION.4
        IF GOOD THEN GOSUB OPERATION.5

Which I personally find far more readable than the indented code.
