Hi Milton,
I can't find any reference to an ISNULL property in the help except with SQL Language.
I also tried ...ISNULL and it is not recognized. It gives and error of "ISNULL property not found".
Of course that does not solve the problem for specifying NULL in HFReadSeek.. value fields.
If that property were available, that would be similar to our previous development language that handled Nulls very well.
Thanks for the response,
