Thus you could get an ISAM record directly into a UDT and vice versa. And you could use an UDT that has only the columns of the ISAM table in the UDT you really needed. I was disappointed this ability was dropped with the ISAM database. I missed it - and still miss it - when dealing with a Jet (Access) database. Helmut. BTW, there was one restriction to UDTs in those days: Strings in UDTs had to be fixed-length strings.

What i'm struggling with now is how to put the function in a utility.bas module so i can use in all projects, then call it from any form. so different forms can declare their own settings type and send them to the same function in the utility module to read and save. If i declare the settings type Private in the form, I cant' pass it to a public module. If I declare it Public I get the error can't do public type in private module. i remember seeing discussions here, but since i wasn't using udts I didn't pay attention searching google now but if any one has the solution I"d appreciate it.
