The SHOW.LIST command displays the content of an active numbered select list, allowing the user to remove unwanted entries.
SHOW.LIST uses a command set based on that of the query processor SHOW command. Using the commands listed below, the user can scroll through the displayed select list items, setting or clearing a marker (displayed as an asterisk next to the item) which indicates whether the item is to be included in the revised select list. All items are initially in the selected state.
The item specification may be
The number shown next to a displayed item.
A range of numbers in the form a-b which indicates that the command is to be applied to all items from that tagged with number a to that tagged with number b. There must be no spaces either side of the hyphen.
The keyword VISIBLE to apply the command to all items on the current page.
The keyword ALL to apply the command to all items in the list.
Multiple item specifications may be included in a single command by using either a space or a comma as a separator. For example "1,4,8-11".
The VISIBLE and ALL keywords may be abbreviated by omitting any number of trailing letters (e.g. VIS or V).
