NAME
	MSG_LEN

SYNOPSIS
	MSG_LEN

DESCRIPTION
	The size of the messages sent during the message network tests
	can be configured with the environment variable MSG_LEN in the
	file psdenv, or by using the length command in PSD.  The
	default message length is 64 Kbytes.

	To change the message length using an environment variable,
	place a specification like the following example into the
	psdenv file:

           MSG_LEN=8192         # data record length set to 8 Kbytes

	It is recommended that you set the value to a multiple of 1024
	(1 Kbytes), with a maximum value of 2097152 (2 Mbytes).  The
	psdenv file is read when the PSD program begins.  If no MSG_LEN
	variable is found, the default length is 64 Kbytes.
