I'm curious about this module type (which JSword does not implement  

RawFiles is stored as a RawText or RawCom module, but rather than  
storing text for a verse reference it stores a number. The number is  
sequentially created starting at 0 and is stored in a file name  
incfile. Each written verse reference gets the next available number  
and creates a file by that number. That is if Exodus 2:3 is the first  
written it is given a number of 1. Then if the next is Matt 5:5, it is  
given a number of 2. And so forth. Each of these numbers becomes a  
file named by that number and the content of the file is the content  
for that verse reference. If the verse reference is being rewritten,  
it just replaces the content of the file.

(As an aside, I first thought this was strange and that one should  
just use RawCom or RawText, but then I realized that re-writing either  
of these causes the module to grow via appending replacement text, but  
this implementation does not.)

I think there is a *tiny* bug in the code that would never be noticed  
by an individual user but when GnomeSword and BibleTime are run on  
different CPUs for the same module it might.

In modules/comments/rawfiles/rawfiles.cpp it has the method:
char *RawFiles::getNextFilename() {
         static char incfile[255];
         long number;
         FileDesc *datafile;

         sprintf(incfile, "%s/incfile", path);
         datafile = FileMgr::getSystemFileMgr()->open(incfile,  
         if (datafile->read(&number, 4) != 4)
                 number = 0;

         datafile = FileMgr::getSystemFileMgr()->open(incfile,  
         datafile->write(&number, 4);
         sprintf(incfile, "%.7ld", number-1);
         return incfile;

The lines:
	datafile->read(&number, 4);
	datafile->write(&number, 4);
are suspect to me.
Do they account for the endianness of the CPU-s architecture?

That is, if a GnomeSword user on a non-Intel box migrates their  
personal commentary to an Intel architecture, will GnomeSword still be  
able to use the module? (Same goes for BibleTime).

In Him,
