Van Snyder's Utilities

Feb 25, 2009
Ed:

Here are two programs you might find useful for getting stuff off the CT
tapes and maybe for other usage as well.

The program skipfile skips a specified number of files on a specified
tape unit.  It can do this with as many units as desired, and even on
the same unit more than once.  It's controlled by card input.  See the
listing.

The program unblock unblocks a file from a specified tape unit and
writes the output to the punch, printer and punch, or another tape.
It's controlled by card input.  See the listing.

To punch the cards in the second file of adc00228-FI-04X, I made up a
deck:

skipfile
011
unblock
0860011P

These are actually 86-character images from one of the Autocoder work
tapes.  The program dropped the last 6 characters.  Autocoder uses
columns 12-15 internally, so I cleared them later with an editor.

To print/punch the stuff in file 3 of that tape, I made up a deck:

skipfile
021
unblock
1330011W
