A QUICK WAY TO CREATE A MEMBER IN AN EMPTY DATASET

Normally, if you are working with a PDS that is populated with members, you can create a new member by going to ISPF option 3.4, entering the data set name, then typing S [new member name] and the command line. Unfortunately, this doesn't work if the PDS is empty. To get around this, go to ISPF option 2 (EDIT), and enter the data set name with the name of the member you want to create like this:

OTHER PARTITIONED OR SEQUENTIAL DATA SET:
   DATA SET NAME ===> 'data.set.name(newmemb)'

I found this gem and some other neat ISPF tricks here.
