I have been asked to program this in RPG.
My question is can this be done in RPG? 
One thought that our network person had who does Java. Is to pass the data from 
the RPG program to Java and let Java do the checking. Then pass a Y (record 
passed) or N (record did not pass) back the RPG program. I could also write the 
record out to a database file then call the that the Java program. Can this be 
done? 
Any and all ideals and help would be appreciated,
