Code:

IF x>7 THEN
  PRINT("TOO HIGH");
ELSE
  IF X<4 THEN
    PRINT("TOO LOW");
  ELSE
    PRINT("JUST RIGHT");
  END;
END;

Now improved with ELSEIF

Code:

IF x>7 THEN
  PRINT("TOO HIGH");
ELSEIF X<4 THEN
  PRINT("TOO LOW");
ELSE
  PRINT("JUST RIGHT");
END;

CASE blocks have similar logic to nested ELSE-IF blocks (exiting the block once a condition is met and relevant actions are executed). It doesn't make your code any shorter but can provide improved legibility.

Code:

CASE
  IF x>7 THEN PRINT("TOO HIGH"); END;
  IF x<4 THEN PRINT("TOO LOW"); END;
  PRINT("JUST RIGHT");
END;
