Re: select vs. if-elseif

I agree about the aesthetics.

I'd point out that COBOL has the same "redundancy" with its IF-ELSE
IF-ELSE
structure and its EVALUATE verb. EVALUATE is the functional equivalent of
SELECT.

EVALUATE A + B ALSO TRUE ALSO X = Z
WHEN 3 ALSO D = E ALSO TRUE
PERFORM PARA-1
WHEN 4 ALSO G = H ALSO FALSE
PERFORM PARA-2
WHEN 5 ALSO J > K ALSO ANY
PERFORM PARA-3
WHEN OTHER
PERFORM PARA-4
END-EVALUATE


I haven't seen COBOL in over 20 years.. now I remember why my old boss
would say "if you want to right a book, use COBOL, if you want to get the
job done, use RPG" exists.
