NEXT SENTENCE & END-IF different in OPM and ILE COBOL

[Vanya Jovic <jovic@xxxxxxxxxxxx>]

Hi ppl,

any ideas why NEXT SENTENCE in IF ... ELSE... END-IF statement behaves
differently in OPM and ILE COBOL?

Both manuals describe same behaviour, and it seems than OPM manual is
wrong.

Example:

IF <something true>
        NEXT SENTENCE
ELSE
        <some statement>
END-IF
<statement A>
<statement B>.   (pay attention to period)
<statement C>

In OPM, on true condition, after NEXT SENTENCE, <statement A> is executed!
In ILE, on true condition, after NEXT SENTENCE, <statement C> is executed!

This was tested with both debbugers (STRISDB for OPM and STRDBG for OPM
and ILE), on V3R7 and V4R3.

According to both manuals, ILE behaviour is correct (... program control
is given to the statement after first period ...).

Any ideas?

P.S. 
        I know, I know, this is wery bad programming tactics, and I
personally cosider NEXT SENTENCE completely redundant, but one can't
choose which legacy programs to maintain. Besides, ILE editor would even
warn if you try to use NEXT SENTENCE and END-IF, but compiler would let
compile with message severity 20. If you don't touch the code, but only
recompile in ILE, without checking the compiler listing, ... you may get
in the big trouble.
