AVFILE
Type: verb
Use: Skip forward or backward a number of files on a tape.
Adverbs:
  INTAPE   Number of tape unit on which map tape is mounted.
           0=> 1
  NFILES   Number of files to skip:
                 NFILES  >  0  skip forward
                 NFILES  =  0  back to beginning present file

file. I.e., if NFILES=1 the tape will be positioned at the
beginning of the next file.
