ADABAS and DB2 Calls in COBOL Program

Hi,

Is it possible for a COBOL program to contain both ADABS calls (EXEC ADABAS) and DB2 Calls (EXEC SQL) ?

If yes, what is the process of compilation for that COBOL program (like Adabas pre-compilation/DB2 pre-compilation/COBOL Compilation…etc)?

Thanks,
Selva.
