You can still order a red reference card from IBM for JCL: SX28-6783-0: OS/360 Job Control Language: Syntax Reference Summary. It costs only a few dollars and is quite handy You can access IBM JCL manuals via the net:
Keep in mind, though, that these are IBM manuals, i.e. the reference won't teach you, it will list the syntax with all its nooks and crannies You might want to start reading with the User's guide - have fun.
You should also keep in mind that the manuals at the IBM site contain the JCL of today, i.e. OS/390 Version 2.10 or later. Many features available today were not around 40 years ago, when JCL was invented. The OS/360 JCL is a (large) subset of the OS/390 JCL
Hercules - an IBM 360/370/390 emulator. You can get a free copy of MVT or MVS to run on it. It boots from Linux or Windows. http://www.corestore.org/hercules.html
