IsBlank or the variable named IsNotBlank.
Simple answer - No.
However, if the original fields are different lengths then there are
techniques you could use.
The more complex (and less efficient) approach would be to interrogate
the descriptors to determine the length passed. But a simpler option,
if it doesn't cause other problems, it to define the parm as Varying
Const. That way %Len(ParmName) will tell you what the length of the
parm was. Don't know enough about what you are trying to do to know
if is of any use for you or not.
