How wonderful it feels when Internet explorer suggests names for URLs when we start typing the first few letters!
Our mainframe also has the ability to do pretty much the same. Using KEYS command on the command line, assign a free PF key with the value AUTOTYPE. We are all set.
Now use 3.4 to go to the Data Set list utility and then type the first few qualifier of the required data set. Press the desired PF key. It will show you the dataset name which is nearest match.
