• Name: Paul Heckbert
  Location: US - United States of America (United States)

To build:

    make all

On System V systems, we had to compile with -Dindex=strchr. To compile on a 16 bit machine, change 300000 to 30000.

To use:

    ./heckbert col < file

where col is the number of columns to fold at and file is the file to fold.

Try:

    ./try.sh

Judges’ remarks:

Folding at the wrong length may be equivalent to a “Spindle or Mutilate” operation. For example:

    ./heckbert 40 < heckbert.c > ph.c ; make ph ; ./ph 20 < heckbert.c > bar.c ; make bar

Try not to Fold, Spindle or Mutilate files. :-)

The judges used this program to fold up very long lines which the BSD fold(1) was unable to process. This program has been added to the contest tool chest.
