MTANAL

     MTANAL is a utility for  determing  the  format  and  content  of
"foreign"  (i.e.,  not  VAX  standard)  magnetic  tapes.   MTANAL will
analyse any number of files on a  tape  and  produce,  for  each  file
processed,  a  summary  of:  the number of blocks within the file, the
minimum and maximum block lengths, and  also  a  hexadecimal/character
dump of the first few bytes of the first block within the file.

The user must first MOUNT the tape with the FOREIGN qualifier, e.g.  :

$ MOUNT/FOREIGN MTA0:

To run the program:

$ RUN VLB:MTANAL

     The user will then  be  prompted  for  certain  parameters.   The
default  values  of  the  parameters are shown in brackets [].  If the
user wishes a default to take effect for a parameter, he simply enters
<carriage return> after the prompt.  The prompts are the following:

File name for listing [MTANAL.LIS] =
Tape Unit (ddcn:) =
Number of files to be skipped [0] =
Number of files to be analysed [32768] =
Title [optional] =
Translate from EBCDIC [no]?

     The analysis stops when the number of files specified by the user
have  been  processed,  the  end  of  the  tape has been detected (two
consecutive file marks), or an error condition has occurred.

     A brief summary is typed on the terminal.  A  longer  summary  is
written to a disk file, as specified by the user.
