Required parameters

The following are the required parameters of the ARCHRCOV macro:

DSN: specifies the address of a field containing the fully qualified name of the data set to be processed. For dsnaddr, use the address of the 44-byte data area that contains the data set name. The data set name must be left-justified and padded with blanks. This data set can be either SMS-managed or non-SMS-managed.
WKAREA: specifies the address of a 200-byte work area that will contain the information specified in the macro. For waaddr, substitute the address of the work area. The work area must be below the 16MB line. The work area serves as a temporary storage area for the macro processing and becomes available to you as soon as the macro returns control to your program.
