Re: IF <var> THEN

Now as : discussed on this group earlier, there IS NO BOOLEAN data type in : Informix. So you can use either SMALLINT or INTEGER. But why use : INT and waste 2bytes, when SMALLINT will do. : ... You can also use the CHAR type, and with the same reasoning: Why use SMALLINT and waste 1 byte when CHAR will do. To make things clearer, I use CHAR as the boolean type, while for single character variables, I use CHAR(1). So there, Informix-4gl does have a boolean type :) ---------------------------------------------------------------------- John H.
