Strange line that did not report a syntax error

[Nancy Palmquist]

Guys,
BTW: Windows 5.0 version of filePro

I was working on a process table and noted the following line - that 
should have thrown an error:

lookup zzz=otherfile k=1 i=a -nx    - this lookup did not fail but found 
a successful record - just so you do not think that is what is broken.  
I think this was a browse lookup but I shortened it for our purposes.

lookup xxx=myfile r=(zzz(@rn) -np

Can anyone spot what should have been a syntax error?  Unless I am wrong 
about the rules, I think this should be invalid.

Nancy
