Answer Posted / xyz
Specifies the amount the workspace required by the
operating system to execute the JOB
Value specified will apply to each step
Formats are:
REGION=<value>K
REGION=<value>M
REGION parameter should only be in units of “K” or “M”
indicating Kilobytes or Megabytes of workspace requested;
Results in JCL error if unit is not specified
If omitted, a default value is assigned by the system
If REGION=0M is specified, the system takes the most
optimum space
