You also can link a user to a window in another IPF .HLP or .INF file. You must specify the file name with the database= attribute. If the following were in the source file, selection of the hypertext link would cause the file, EDITOR.HLP to be loaded, and the window whose ID is 001 to be displayed.

:link reftype=hd database='editor.hlp' refid=001.

:elink.

The heading definition in the other file must contain the global attribute. If the link to the file cannot be resolved, the hypertext phrase in the link is not highlighted. For example, if the .INF or .HLP file is not available, IPF will not highlight the linked phrase. If the .INF or .HLP file becomes available, IPF will dynamically highlight the phrase.
