New syntax encountered

Hi,
I have encountered the following code in a program

If +Top-fourgous=''
+Top-fourgous='N'
...
End-if

What does it means ? Does it implies an AND or OR between the 2 conditions ? Or does it means something else ?

Thanks

The "+" sign is an accepted method among NATURAL programmers to define an AIV (Application Independent Variable) or Global variables.

Hi Ofer,

I understand that AIVs are acceptable in Natural. But my doubt is about the If condtion statement. what does the conditional statement mean?

Could you please try to help me?

It checks wheater the variable "+Top-fourgous" equals blanks.
