HOW TO USE THE MAINFRAME.
Download the free program wc3270 for windows. Install it. Set up a connection to cyberdatastorm.com:3270. Your logon ID & PASSWORD will be USER100 & PIZZA OR USER101 & TACOS . You will have access too JCL, COBOL, ASSEMBLY, C++, REXX, and will be able to use the SYSDUMPs. You will be on sysplex1 with full access to 3380, 3390, and 3350 DASD. You will also have access to IBM 3420 TAPE Unit. You can explore what a mainframe operating system is like and how it is different from personal computers. Obviously you will not have access to TOP SECRET or RACF. I often say that anyone can learn PC stuff (personal computers) like Linux, Windows, or Apple OSX by reading just 1 thick 2000 page book. But for the mainframe you need to read about 200-300 of those thick 2000 page books. It is way more complicated. There are 5 mainframe operating systems: IBM Unix called AIX, IBM vm/cms, IBM os/400, Digital Equipment Corp VMS, and the Zos family. This mainframe you are logging into is in the Zos family. It does support full ISPF/TSO and CDC's (cataloged datasets). You will not have access to easytrieve, expediter, endeavour, and CICS.
