Fomus
Data
This produces a file with extension .fms containing a dump of the data
that is sent to fomus before any processing occurs. If this is the only
output specified, fomus simply saves the data and returns without
further processing. It may be specified using either the :data or
:fomus keywords in the output setting. The file is editable and can
be reloaded for editing and processing by calling the fomus function
with the name of the file. See Text File Interface for a description of
this file format.
