RE: Import taking over 24 hours -- RPG400-L

The database engine they are using is strictly a runtime, acucobol, and they 
will not provide us any additional info on the file layout.  We have 
confirmed that many of the fields are binary which means we cannot read them 
directly.

We are using Access just to dump the data out, their program is a cobol 
program written using acucobol, and no we don't have the source to that 
either....there is no way they will give us anything except the obj 
files.....we even tried talking to acucobol but they referred us back to the 
developers and said that since we are a customer of theirs they are under a 
contractual obligation ** NOT ** to assist us with any questions.  Which to 
me is baloney.....
