Is this a sequential file or a binary file?  Is that byte
on line 25 always at the same location - I.E. 300 bytes
into the file (or whatever)?  If so, you can use a binary
PUT to change it:

     OPEN "B",1,FileName$
     SEEK 1,300
     A$ = "2"
     PUT 1,,A$
     CLOSE

If it is a sequential file, you can input the lines and
save to a temporary file until line 25, and then change it:

     OPEN "I",1,FileName$
     OPEN "O",2,TempFile$
     FOR i = 1 TO 24
          LINE INPUT #1,A$
          PRINT #2,A$
     NEXT
     LINE INPUT #1,A$
     PRINT #2,"2"
     DO UNTIL EOF(1)
          LINE INPUT #1,A$
          PRINT #2,A$
     LOOP
     CLOSE
     KILL FileName$
     NAME TempFile$ AS FileName$

Make sure that TempFile$ and FileName$ are on the same
drive as the NAME command does not work across drives, but
does work across directories.
