Keywords: DOS pipes |
Summary: pipes are *files*

Whenever you use the | DOS uses a temporary file for the output
of the first program. It then uses said file for the input
of the second program. After the second program is finished
DOS kills the file. 

Thus the write protect error. You can also crash a pipe if there
isn't enough space left on the disk. Pipe file names are *weird*.
