status.i4.v = acl_log_file_c(log_file.i1a.r, options.u4.v)

	This routine sets the log file for Accelerator Command Language
	(ACL) scripts.  The log file argument to 'acl_execute_c' can
	override this value.

	log_file	fully specified name of log file to generate
			(If a value of NULL is passed for this argument,
			 the log file option will be turned off.)
	options		log file options
			(ACL_OPT_NONE -> no options selected)

	This function returns ACNET status values as follows:

	CLIB_OK			success
	CLIB_INVSIZ		file name too long

	This function requires the following include files:

	acl_h, acnet_errors.h
