}Both kludges are really pretty awful, but I have no better ideas right

]What's awful about putting your strings into string list resources?

What's awful is that most (all?) of the existing HyperCard resource
movers, XFCN installers, etc., will copy only your XFCN or XCMD, without
checking to see if there are any 'STR 's or 'STR#'s with the same number.
Perhaps it's time for Apple to roll out those RSV[12]s for X*s, but until
and unless some method of associating X*s with their owned resources
becomes a standard, don't use extra resources if your code is meant to
be user-installable.  Lost are the days when we can assume that anybody
installing or moving resources is a hacker with ResEdit.
