The DYNAMNBR parameter is used to indicate how many Task I/O Table
(TIOT) slots to reserve for data sets that may be dynamically
allocated during the job step.

The TIOT contains control blocks for every DD allocated in your jobstep ( dynamically or via JCL ) .

If you fill the TIOT, no more files may be allocated until some are unallocated. TIOT size varies based on operating system settings.
