[EpiData-list] Complex if statements (was chk file with calculations ....)

For the suggested chk file command:

IF N9SUICIDE = 3 or (N9SUICIDE = 2 AND TOTAL >= 16) or TOTAL > 42 THEN ATRISK="Y" ELSE ATRISK="N" ENDIF

I would always write:

IF ((N9SUICIDE = 3) or ((N9SUICIDE = 2) AND (TOTAL >= 16)) or (TOTAL > 42)) then

most likely this would/should also work:

IF (N9SUICIDE = 3) or ((N9SUICIDE = 2) AND (TOTAL >= 16)) or (TOTAL > 42) then

In other words: Always be very explicit with parenthesis.

Test and report please.
