Re: Why you shouldn't be afraid to use VARCHAR in RPGLE

Hi Daniel

You can have a single (overloaded) function if instead of using the return
value you pass the result (char/date/time/ts) as a parameter by reference.
Of course you need a separate function for numbers.


Best regards

Hi Birgitta,

%IF does not (yet?!) exist.
But it would be easy to code ... and for different data types the

function can be overloaded.

Well - yes and no - of course you can overload the input parameters - but
until now, it is impossible to also override the return value type. All
procedures (functions) in a override have to return the exact same type. So
you would have to create different functions vor each return type.

ifChar( 1 = 1 : 'Hello' : 'World' );
ifInt( 'Y' = 'N' : 1 : 0 );

... and so on. So a %BIF would be much easier, as it could return an
arbitrary type.

Daniel
