OR-ITEMS Command (English) (m618305+oritems.htm)
Returns a list comprising one copy of any value contained in any of two or more items, that is, the union of the values.
OR-ITEMS file-specifier {item-list} {(options}
file-specifier Specifies a file as defined in General Conventions.
item-list A list of item-ids or an asterisk (*) for all items. Can be omitted there is an active list from a preceding list-generating command.
I Specifies that case should be ignored when comparing attribute values.
S Specifies that case is significant when comparing attribute values.
Only the first field (value or subvalue) is processed, all the other fields being discarded. The merged list therefore contains only the first field from each attribute.
If neither I nor S is specified, the current data case setting (set with the DATA.CC environment option or the CASE TCL command) is used. See Case Sensitivity for more details.
If both I and S are specified an error message is displayed and no list is generated.
