# lfsb macro

This macro is the same as the lfsi macro
except that the i-fms column becomes index-fms. index-fms is the number
of frames in the index only. That is, the number excludes the number
of frames used in the file.

Note: This macro only applies in situations where the file-save was run with both the b and s options.
