What Is Disp=mod ? |
|
Answer» DISP=MOD modifies a sequential data set. It is a CONVENIENT way to add data to the END of sequential dataset. If the data set doesn’t exist, the system changes MOD to NEW UNLESS the VOL parameter request SPECIFIC volume. When VOL is coded, the stem expects to find data set on the specified volume and terminates the step if it cannot find it. MOD is the usual way of extended data sets in to several direct-access VOLUMES. DISP=MOD modifies a sequential data set. It is a convenient way to add data to the end of sequential dataset.
