RE: R: RPG Indicators

[Jon Erickson <jerickson@xxxxxxx>]

The only problem I find using the %BIF Indicators is during a debug session.
Yes, I can use an indicator in conjunction with the %Found or %EOF. But why?

Sometimes it nice to be able to manipulate the indicators during debug
sessions testing each path a section of code may take dependant upon thier
status.  Sure beats having to build all the test data scenarios.

Just .02 worth, maybe less.

 >>  I come back to indicators.  What do you think about this?

I think that there is no reason to use indicators at all any more except
where
dictated by the compiler (e.g. LOOKUP) and even then you don't have to _use_
the
indicator afterwards, it is only needed to qualify the operation.

I'm not sure why so many people seem to be confused over the use of %Found.
The
built-ins map on a one-to-one basis with the old indicators, so it is all
very
straightforward.  %Found is only set by operations that can set the "No
Record
Found" (NRF) indicator (e.g. CHAIN).  Since READC does not set the NRF
indicator
it does not set %Found either.

The basic plan is this:

%EOF - set whenever the EOF indicator would have been set.

%Error - set when the (E) extender is used _and_ the error indicator would
have
been set

%Found - the opposite of the NRF indicator - set when the indicator would
have
been off and vice-versa
