	Many compilers support the sub GETARG which will 
retrieve character strings from the command line.  
==========
	PROGRAM ReadCmndLine
	INTEGER    I
	CHARACTER  PARAM1

	I = 1
	CALL GETARG(I,PARAM1)
==========
	By indexing I you can retrieve multiple parameters from 
the command line.  
	Hope that helps!
