Is there a CPU savings when one converts from OS/VS COBOL to Enterprise COBOL?

IBM COBOL and Enterprise COBOL performance are approximately the same. You might see improved performance in COBOL for MVS & VM and COBOL for OS/390 & VM and later for static and dynamic calls, and in COBOL for OS/390 and later for programs compiled with TRUNC(BIN).
