this is a great trick ive used on several cdrom projects with hypercard
that were very text intensive (one was an encyclopedia, so lots of text).
really helped the load speed by reading the bulk of the text from text
files using rtf instead of holding them in fields. also helped what i
think was memory issues with the several externals we were using when
testing for extended use periods.
cheers,
jeff
