Let JCOKE = 98 and LPEPSI = 42 Consider the statement
IF (JCOKE - 3 * LPEPSI) 5, 6, 7
5 JCOKE = JCOKE + 5
6 JCOKE = JCOKE + 8
7 JCOKE = JCOKE + 11

Execute negative, if the expression results in negative.
Execute zero, if the expression results in zero.
Execute positive if it results in positive.
Execute negative, if the expression results in negative.

Any non-zero number in the 'if' statement is evaluated as 'True'.
Hence, if (-28) is true and the statement associated with the if statement is executed (here since there is no brackets only line 5 is under the control of the if statement and will get executed and line 6 and 7 will not get executed.
