Parameters
[REV BEG]
item The names of the valid items or range of items in the data
register that are to be displayed. These items can be
child items.
subscript A list of numerical values of the form val1, val2,...valn
used to select a particular element in an array. If this
parameter is omitted and the item being displayed is an

Discussion
This command allows you to display either selected items in the data
register or all the items in the data register. The item values are
converted to their ASCII equivalents prior to display. If an item cannot
be successfully converted to ASCII or an overflow occurs, the item value
appears as #s.
If an item cannot be displayed entirely on one line, it is formatted for
multiple lines. If the items being displayed cannot fit on a single
screen, a CONTINUE(Y/N)? prompt is displayed at the page breaks. If an
item name is not specified, all the items in the data register are
displayed.
NOTE Child items cannot be used when specifying a range of items to
display.

The following examples display a single item, a range of items, and all
