Re: Interesting restriction on the rules between releases

I'm kind of curious as to what value the caller received if the 2nd
return was executed. Zero perhaps?

The program ends with RNX0224:

Folks:

I just noticed something interesting ... some rules got tightened in
the RPG compiler between V5R4 & 6.1.

We have a procedure that returns a 4,0 number ... the prototype &
interface both specify the return value.

The procedure is coded with multiple exit points. One in the middle
of the logic (a short circuit exit) and another at the very end.

The short circuit exit is coded as 'return value;'. The exit at the
end is just a 'return;'. Clearly a coding error.

On the face of it, I would expect this compile to fail due to the
lack of a return value on the 2nd return. But, on V5R4, it doesn't.
The compile WILL fail if neither of the return statements specify a

value.

On 6.1, however, the compile DOES fail because the 2nd return
statement doesn't specify a value.

I'm kind of curious as to what value the caller received if the 2nd
return was executed. Zero perhaps?
