Compiling VARPG to Java - errors about SDS and INFDS statements

["Flagler Jr., Richard E." <flagler@xxxxxxxxxx>]

The following code is a snippet from the Browsed Compile Listing of VARPG. 
I am attmpting to recompile an existing, fully debugged application from VARPG 
to JAVA. I know the compiler doesn't support the OVERLAY keyword in 
the "D" specifications but can anyone assist with solving these compiler 
diagnostics about INFDS and Ssystem DS? This compiles and runs fine with 
regular VARPG
but compile failes in Java. Thanks. RF
