To address a record in the LINKAGESECTION, pass an argument to the program and specify the record in an appropriate position in the USING phrase in the program.
If your program has the RECURSIVE attribute or is compiled with the THREAD compiler option, data that is defined in the LINKAGESECTION is not accessible on subsequent invocations of the program.
