GET-INDEX
Opens an index for subsequent use by ENGLISH and certain TCL verbs. Rather than generating a select list, as SELECT-INDEX does, GET-INDEX starts a traversal of the index to supply item IDs to the immediately-following English verb, as required. This improves performance when compared to SELECT-INDEX, particularly when using remote indexes, since it does not build a select list in advance.
Note that because GET-INDEX does not build a select list, the SAVE-LIST command cannot be used after a GET-INDEX.
Command Class
TCL-I command.
Syntax
GET-INDEX file-specifier index-name
Syntax Elements
file-specifier Specifies a file as defined in Conventions, except that file modifiers cannot be used because indexes are only definable on data sections.
index-name The name of the index.
