F77 program to recover a corrupted ANSI magtape. Allows you to read it file
by file (or block by block if need be), with an option to continue on error
(unlike PIP or COPY, which just give up). You can read past the header of an
accidentally INITIALIZEd tape, and recover the old files. The program might also
be used to read ANSI magtapes on a system SYSGENned without ANSI support, and
with a little work, might be made to run on non-DEC systems, since DEC are the
only people I know to actually USE the ANSI tape standard!

ANSITAPE.F4P and ANSICOM.F4P are an FORTRAN-FOUR-PLUS version. This is slightly
older that the F77 one. There were some minor mods done in the translation, but 
I can't remember what they were!

Bugs
----
Does not yet allow for HDR3 and EOF3 blocks -- they are rejected, and you have
to tell the program to ignore them. It shouldn't be difficult to make the
program ignore them, but I haven't destroyed a magtape lately, and so it hasn't
got done.
