The conditional expression and selection statement. Use of explicit scope terminators is recommended. COBOL conditional expressions allow shortforms, where the current identifier (and conditional) is assumed through multiple condition tests, unless explicitly given.
IF A = 1 OR 2 ...
is equivalent to
IF A = 1 OR A = 2 ...
IF A = 1 OR 2 THEN perform miracles END-IF IF A = 1 OR 2 AND B = 1 THEN perform rites-of-passage ELSE perform song-and-dance END-IF
IF statements can be terminated with full stop or explicit scope terminator
END-IF. Use of periods for scope termination is no longer recommended. Full stops mean just that in the case of nested IF, all nesting is terminated at the first full stop
., and any subsequent code will be outside the IF block.
