### 8.4.3 Specifying cross-reference jump destinations

Mif2Go 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:

[HelpOptions]

; XrefFileSuffix = suffix to use (no leading dot)

; when converting [HelpXrefFiles] xrefs

XrefFileSuffix=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 = ugmif2go
