Обсуждение: 8.0.0 beta 2, void type

            I have moved a DB from 7.4.3 to 8.0.0b2 for testing and am
experiencing some
            problems with the void type within pl functions.  I am calling a
function which
            returns a void from within another function and have defined a
variable of type
            void to catch the returned value.  This worked fine in 7.4.x but
when executed
            in 8 generates a "variable has pseudo-type void" error.  Is this
a bug or a
            change in functionality?  Is there a workaround short of
rewritting all
            functions to return a non-void value?

            thanks,

            Nick

Er, why would you want to catch a void return value?  Seems like
you ought to use a PERFORM statement.

I didn't know about PERFORM so was just doing what I discovered would work.
Thanks for the tip.
