Parameters

data-id: The variable in which the data ID that uniquely identifies the data set is stored.
DISPLAY: Indicates to LMMDISP that it is to create a member list if one does not exist and display it.
pattern: The character string that is used to specify which members are to be displayed. See the z/OS V2R2 ISPF User's Guide Vol I for a more complete description of patterns and pattern matching.
YES|NO: Indicates if LMMDISP is to return member statistics via dialog variables. See Dialog variables for a list of the dialog variables.
panel-name: The name of the panel on which the member list is to be displayed. See z/OS V2R2 ISPF Planning and Customizing for the requirements for customized panels. If this option is omitted, the panel is ISRML000.
ZCMD|ZLLCMD|ZLUDATA: The name of the field on which the cursor is placed when the member list is displayed. If ZLLCMD or ZLUDATA is specified, the cursor is placed on that field of the first member to appear on the display.
top-row: The name that designates which member is to appear first on the display. If the member cannot be found and the list is sorted by name, the member immediately preceding the requested one in the member list is scrolled to the top. If the list is not sorted by name and the member is not found, the list is scrolled to the top.
S|ANY: S indicates that LMMDISP is to allow only S as a valid line command for member selection. ANY indicates to LMMDISP that any character or character string is a valid line command.
1|9: Indicates to LMMDISP the length of the Line Command field on the member list display.
If 9 is specified and the data sets associated with the specified data ID have formatted records, the Created field is left out of the member list display. If the data sets do not have formatted records (RECFM=U), the Alias field is left out of the member list display.
buf-len: A fullword fixed binary integer containing the length of the buffer parameter.
buffer: A buffer containing the name of the service and its parameters in the same form as they would appear in an ISPEXEC invocation for a command procedure.
ALLOWNEW: Indicates that nonexisting members can also be selected. Omitting this parameter causes only existing members to be selected.
