Aren't most GUI controls 'bound' to a data source? In other words, load
their own data.

No. These days, in languages other than COBOL, they certainly are, but in
PowerCOBOL I don't think there was a facility to bind to a datasource. (I
could be wrong...) All of the PowerCOBOL I've seen doesn't use bound
datasources. Anyway, it doesn't matter; I have inspected the code and they
don't use bound datasources...

Pete,

Just for the record, POWERCOBOL does allow bound controls, in at least
version 8. Not sure now about version 7 and earlier, and cant easily
check it as I don't have the installer at hand.

But my personal advise on this is NEVER to use them in ANY language
whatsoever. And this is based in personal experience of the headaches
one has when using them.

That may be good advice :-)

I have used bound controls occasionally in C# with SQL Server, and it has
worked perfectly. But I have only done very simple things with them.

Thanks for the clarification on PowerCOBOL.

Pete.
