ISPF option 3.3 provides the Move/Copy Utility that allows copying data from one dataset to another. This option supports both sequential and PDS datasets and is commonly used for dataset operations.
Under ISPF's Utilities menu (option 3), option 3.3 is the Move/Copy utility, which lets you copy members or entire data sets from one location to another, distinct from options like 3.2 (Data Set) or 3.4 (Data Set List) which serve different utility functions.
