	4244	MRB	7-Feb-86
		Files are always written in .IODMP mode. They must have the 
		user selected mode recorded in the FDB.  When closing a file 
		(on a TOPS-10 system) we should look at the I/O mode specified 
		by the user and perform a rename FILOP. to set the proper 
		I/O mode in the FDB.
		
	4246	MRB	11-Mar-86
		CORRECTION TO EDIT 4244! When closing a non-disk unit we should
		NOT do a rename FILOP.

	4247	RJD	11-Mar-86
		Make the error "FRSOPN Can't open file: Too many open units"
		a fatal error.

	4250	MRB	17-Mar-86
		Add an additional check to the routine that checks to see if this 
		is the controling terminal.  This new check will see if the job
		is detached. If the job is detached we shouldn't to a DEVST JSYS
		because, this JSYS will wait until a controling attaches to the
		job to return. If the job is detached just jump to NOTTTY 
		because a detached job cannot have a controling terminal.

	4251	MRB	1-APR-86
		Yet another CORRECTION TO EDIT 4244! When closing a disk unit
		which is opened for input only we should NOT do a rename FILOP.	
		Also,problems with renaming the dates&time fixed.
