  There is a lack of a feature in CPM that I hope exists in MARC: It is
impossible to return to the disk operating system any part of a file that
is no longer being used.  For example, one can't cause a file to be
shortened by returning all allocated disk blocks after a particular point
in the file.  Does MARC have a system call to do this?

  If anyone knows an easy fix for this in CPM, please let me in on it.

Thanx -Cliff
