This appends all of the frames of the specified page to the output file, in the format specified.
Frames are written in numerical order, and missing frames are skipped over.
If the output type is ASCII, OvationPro, or HTML and the frame has no header (line 1), then all blank lines will be removed as the frames are copied out. You should blank lines using the omitline() command.
If the output type is OvationPro, you should have either created your own DDL header, or output the standard one with filewriteovnhead().
Likewise, if the output type is HTML, you should have either created your own HTML header, or output the standard one with filewritehtmlhead().
This command reads the cached frame, thus you must call storeframe() after modifying the frame contents in order to ensure the cache is up to date with respect to your modifications.
