The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Good to know. Not intuitive, to me, anyway. I suppose an indicator is as close to boolean as RPG offers. It does make sense that the signature would be wrong. There must be a type conversion chart in a reference manual somewhere we could point people towards.

The code looks pretty good, syntax-wise.
dbmd must be a reference to a java object derived from aConnection.getMetaData().
unique and approximate are going to have to be hex '01' or hex '00'. 1N is an indicator type. In RPG an indicator is either hex 'F1' or hex 'F0'.
If you code the parameters as 1N, RPG will take care of the conversion between RPG indicators and Java booleans.
And it wouldn't work anyway to use A instead of N on the prototype. That would cause RPG to create the wrong signature for the method, using B
(byte) instead of Z (boolean). You'd get a method-not-found error on the call.
