#### 17.4.3 Specifying cross-reference jump destinations

DITA2Go uses a reference number to produce a jump from a cross reference. For interfile cross references to or from the help file you are producing, you must specify the names of all the topic files involved, in the form topicfile=helpfile; for example:

    [HelpXrefFiles]
    ; file name in xref = file name for .hlp
    chap1=chaphelp

You can specify a file extension for the destination help file; the default is hlp:

    [Setup]
    ; FileSuffix = suffix to use (no leading dot)
    ;  when converting [HelpXrefFiles] xrefs
    FileSuffix=hlp

You can specify a name (without file extension) to use for any topic files not listed, as XrefFileDefault=helpfilename. You can use this setting for your own usual help-file name, so you do not have to name this file explicitly under [HelpXrefFiles]. For example:

    [HelpOptions]
    ; XrefFileDefault = name of file to use for missing XrefFiles
    XrefFileDefault = dita2go
