B IF Mark >= 50 THEN OUTPUT "Pass" ENDIF

2. How far is THEN indented from the IF line?

A Two spaces

B Four spaces

A Lined up with THEN and ELSE

B Lined up with the IF it closes

4. Which layout positions ELSE correctly?

A IF Age >= 16 THEN OUTPUT "Adult" ELSE OUTPUT "Child" ENDIF

B IF Age >= 16 THEN OUTPUT "Adult" ELSE OUTPUT "Child" ENDIF

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1IF Age >= 16 THEN OUTPUT "Adult"		AENDIF is indented two spaces. It must line up with IF, in the same column.
2 ELSE OUTPUT "Child"		BTHEN is on its own line, two spaces in from IF. The statement inside THEN is indented further.
3THEN and ELSE are two spaces in from IF, the statements inside are indented further, and ENDIF lines up with IF.		CTHEN is not indented. It must be two spaces in from IF, with the OUTPUT statement indented further.
4A nested IF keeps the same two-space step. The inner IF sits inside THEN and its own ENDIF lines up with the inner IF.		DELSE is on its own line, two spaces in from IF. The statement inside ELSE is indented further.
5IF Score >= 50 THEN OUTPUT "Pass" ENDIF		EIF Age >= 16 THEN IF Age >= 65 THEN OUTPUT "Senior" ENDIF ENDIF
6IF Score >= 50 THEN OUTPUT "Pass" ENDIF		FIF Score >= 50 THEN OUTPUT "Pass" ELSE OUTPUT "Fail" ENDIF

Answer Key

Indenting THEN and ELSE by two spaces

Section A: Quick Questions

A — IF Mark >= 50 THEN OUTPUT "Pass" ENDIF

A — Two spaces

B — Lined up with the IF it closes

A — IF Age >= 16 THEN OUTPUT "Adult" ELSE OUTPUT "Child" ENDIF

B — Further in than THEN

Section B: Match the Pairs

IF Age >= 16 THEN OUTPUT "Adult" → THEN is on its own line, two spaces in from IF. The statement inside THEN is indented further.

ELSE OUTPUT "Child" → ELSE is on its own line, two spaces in from IF. The statement inside ELSE is indented further.

THEN and ELSE are two spaces in from IF, the statements inside are indented further, and ENDIF lines up with IF. → IF Score >= 50 THEN OUTPUT "Pass" ELSE OUTPUT "Fail" ENDIF

A nested IF keeps the same two-space step. The inner IF sits inside THEN and its own ENDIF lines up with the inner IF. → IF Age >= 16 THEN IF Age >= 65 THEN OUTPUT "Senior" ENDIF ENDIF

IF Score >= 50 THEN OUTPUT "Pass" ENDIF → THEN is not indented. It must be two spaces in from IF, with the OUTPUT statement indented further.

IF Score >= 50 THEN OUTPUT "Pass" ENDIF → ENDIF is indented two spaces. It must line up with IF, in the same column.

Section C: Definitions

THEN — THEN and ELSE sit two spaces in from IF, on their own lines. The statements inside each go further in, and ENDIF lines up with IF. Nested IFs keep the same two-space step.

Section D: Fill in the Blanks

IF Score >= 50
  THEN
    OUTPUT "Pass"

  THEN
    OUTPUT "Pass"
  ELSE

  ELSE
    OUTPUT "Fail"
ENDIF

IF Mark >= 50
  THEN
    OUTPUT "Pass"

        OUTPUT "Merit"
      ELSE
        OUTPUT "Pass"

Section E: Spot the Error

C — THEN is already on line 2, on its own line two spaces in. The statement inside it must go on its own line, indented further to four spaces: ' OUTPUT "Adult"'.

A — THEN must not be written on the IF line. It goes on its own line, indented two spaces in from IF. Line 1 should be just 'IF Score >= 50'.

C — THEN sits on its own line, two spaces in from IF. The statement inside THEN belongs on the next line, indented four spaces: ' OUTPUT "Hot"'. The line should be just ' THEN'.

C — ENDIF must be on its own line, lined up with IF at the left margin. It must not be added to the end of the statement line. The line should be ' OUTPUT "Well done"'.

B — THEN stays on its own line, two spaces in from IF. The statement inside it goes on the next line, indented further. Line 2 should be just ' THEN'.
