Differentiate COBOL and COBOL-II. (Most of our programs are written in COBOLII, so, it is good to know, how, this is different from COBOL)?

The following features are available with VS COBOL II: 1. MVS/XA and MVS/ESA support. The compiler and the object programs it produces can be run in either 24- or 31-bit addressing mode. 2. VM/XA and VM/ESA support the compiler and the object programs it produces can be run in either 24- or 31-bit addressing mode. 3. VSE/ESA supports the compiler and the object programs it produces can be run under VSE/ESA.
