Type a partial name (zero or more characters) into a Library field
(project, group, type, or member) or the Other Data Set Name field.
Press the function key that has been set to AUTOTYPE. ISPF sets
the field to the correct value.
If you immediately press the function key again, ISPF retrieves
the next data set or member name. Up to 100 data set names and 700
member names can be retrieved.
