Thanks for the input, Jonas, and I went through all the declarations and found that AUNode from the AUGraph.h was wrongly specified as "Integer", and should be SInt32 as used in the C sample. That did a huge difference, and the sample is now works. Thanks again, Normann > Jonas _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
