I wrote the following long ago:

         map (t) Z9$=2
         map (t) word w1%

         input "Saveset name"; F$

         open F$ for input as file 1%, &
                 organization undefined, &
                 recordtype any, &
                 access read

         get #1%
         r% = recount
         field #1%, r% as buff$
         z9$ = mid(buff$,41%,2%)

         print "Saveset blocksize is: "; w1%

         close 1%

         end

So, any file can be opened.  I believe I got the correct location of the 
blocksize.  So, the question I'd ask is, why cannot BACKUP do this 
simple check, and then ask the user if he/she wants BACKUP to re-set the 
info and then use the file?  Yeah, not all files will be save sets, and 
some sanity checks could be added, but at least the user could have this 
done with a verify inquiry.

Just seems so reasonable ...
