RETURN command?

[tenaja]

Hi,

The strange thing is that the PBP compiler does not detect a missing RETURN instruction at the end of a sub.
No warning or error is raised. With a complex program it can take some time before this kind of vicious bug is detected.
Maybe something to correct with a future release of PBP (if any ?)

Why, or how would it?

You are allowed to put labels in the middle of a sub so you can do a conditional goto, etc. So, a label is not an acceptable terminator for a sub. So what would you use?

I haven't kept up with pb's recent changes, but if it doesn't have functions with parameters, there's no way to easily force an error if you skip a return.

Especially since you can have many Return statements shielded by conditional blocks.

The best way to force correct programming is through functions. Last I looked, PB didn't have them.
