DSXchange

I'm working on the mvs edition,
Does any one know how can I change the default values of a fixed withed flat file such as unit?
I want to change the default value of unit from sysda to something else/

SYSDA = UNIT, other possible value is TEMP.

UNIT parameter basically tells where exactly on a volume you are storing your data set and when you specify UNIT =SYSDA it means you are storing on permanent storage there.

When you specify UNIT = TEMP, it means its a temporary storage on your volume where you are storing the dataset.
