Everything for IBM 360 mainframe, including JCL, COBOL and Fortran is in https://www.amazon.com/Programming-IBM-360-Clarence-Germain/dp/B0000CO6X1/ https://www.amazon.com/Programming-IBM-360-Clarence-Germain/... (cheaper on eBay) Never used COBOL section though, but everything else was excellent: jcl, Fortran and how to operate the equipment.
