A user is submitting jobs to our Cray X-MP & Y-MP from an IRIS 4D workstation.
He has written simple UNIX shell scripts with rsh commands to execute commands
on the Cray.  Things get out of desired sequence when the commands for the
Cray are FORTRAN.  His example:
		WRITE (6,' PROMPT CHARLIE (0/1)')
		READ (5,*) IRESP
		STOP
		END
When run interactively on the Cray, he types the name of his executable and
gets:
		testrsh.e
		 PROMPT CHARLIE (0/1)
		1
		  STOP
		CP: 0.001s, Wallclock: 3.808s

where the 1 is his input in response to the read prompt.

Trying the same thing using rsh, he gets:

		rsh lercymp testrsh.e
		 1
		  STOP
		PROMPT CHARLIE (0/1)
		 CP: 0.001.s,  Wallclock: 8.670s

After typing the rsh, the terminal seems to hang ... but it is open to read
standard input.  So, when he types 1 it proceeds, with the prompt appearing
later.  

The user's question:  WHY DOESN'T THE PROMPT GET WRITTEN BEFORE THE KEYBOARD
OPENS FOR THE READ?  E-mail replies will be welcomed.  Thanks!
