%date() parameter confusion

Hi all,

I found the following in the (WDSc help) documentation for the %date() 
BIF:
"The second parameter is the date format for character or numeric input. 
Regardless of the input format, the output is returned in *ISO format."

So, I tried doing this:
%date( inDate : inType);

(where inType is a 4A field) to convert a given 6,0 numeric field (passed 
from another program) to *ISO, based on the type (also passed by the 
caller).

The result was the compile error:
 *RNF0606 .... The second parameter for %DATE is not valid.

Is this a problem with the definition of the 'inType' field, or did the 
documentation fail to mention that the second parameter must be known at 
compile time?
