	TRU truncates files.  Though PIP will also truncate files, PIP will
change the revision date on all files specified, even if they did not
require truncation.  This will cause an incremental backup program (such as
BRU) to needlessly backup files which have not been changed.  TRU first
ascertains whether or not a file requires truncation before invoking
PIP to actually do the truncation.

	NOTE:  THIS PROGRAM REQUIRES THAT A SCRATCH DIRECTORY LB:[12,1]
		BE AVAILABLE TO ALL USERS.

	This program runs under IAS v3.0.  To use under RSX-11M, replace
the object runsys.obj with the object produced by runsysrsx.ftn.
To use under multi-user IAS systems, replace the object
runsys.obj with the object produced by runsymu.ftn.
