In order to display information about Large Files, two new file format options have been introduced. The LISTF, LISTFILE, and LISTFTEMP commands now support options 10 (SUMMARYWIDE) and 11 (DISCWIDE). File format option 10 is the Large File equivalent of file option '1', containing all the same information, but in a new format that allows for the expression of larger values. Similarly, the format option 11 is the Large File equivalent of file option '2'. Again, the same basic information is displayed, but the format has been changed to allow for a greater range of values to be displayed.
