James, I'm a quick learner.....Learn we what a Datalink field is and how this could help me.
A Datalink field is a field in a database file, that explicitly points to some other object (generally in the IFS), in a way that is managed by DB2. It was introduced after V4R2, but by V4R4.
As I recall (and it's been a few years since I dabbled in datalinks), to create a file with datalink (or BLOB or CLOB) fields, you have to do it from SQL, rather than from DDS, and you have to either have journaling enabled on the library, or use special options to bypass a lot of the checking DB2 does on datalinks, in order to do it.
I'm sure there's someone else who knows more about datalinks than I do; all I managed to accomplish with them was to get QuestView (tm) to provide minimal support for them.
At any rate, from what I've said, it should be clear that a datalink field would allow you to put a protected reference to your captured signature image into a database, and assuming you need to deal with the file from a terminal environment, it would certainly be easier to deal with than sticking the image into a BLOB (binary large object) field.
