One block constitutes 32KB of formatted memory.
Nope. Not even close. Memory is a specific term used on IBM mainframes to refer to storage available to the central processing unit -- not disk space, not tapes, nothing but bytes used by the CPU and controlled via the REGION= parameter.
Furthermore, except for some specialized cases, 32760 is the limit for a data set block size, not 32K.
There is a link to the manuals at the top of the page, click on it and read the JCL Language Reference and User Guide manuals. These will tell you about requesting disk space.
