invalid argument system runtime error on line with variable lookup

[Bruce Easton]

I'm getting a filepro runtime error:

 *** A System Error has occurred ***
 on file: \dvr/filepro/DEUDAS/map
 Line: 1407  invalid argument

from an rclerk process (Windows fp ver. 5.07)

where line 1406 and 1407 in the processing are:

  If:
Then: fileq = filen{"@"{qual{""
----- -  -  -  -  -  -  -  -  -  -  -  -
  If: 
Then: lookup readd = (fileq) r=rv -n 

rv is declared as 8,.0
fileq at the time it hits here should hold: DEUDAS
and qual should be blank

I haven't been able to test with debugger since 
the system error comes up right away.  When I insert 
lines above the problem line, the error message 
follows that same lookup line.

This is a clerk process that runs out of another 
file (not DEUDAS) and runs from @menu straight down 
to the problem point.

Any ideas?
