C NAME:
C	ArrInfo
C PURPOSE:
C	Perform simple calculations on arrays
C INPUTS:
C	All function take integer arguments for the array size;
C	one or more arrays and/or one or more constants
C	The types of A,B, R,R1,R2 depend on the function called.
C
C	N		integer		array size
C	A(N),B(N)	depends		source arrays
C	R,R1,R2		integer/real	constants
C
C OUTPUTS:
C	The type of C depends on the function called.

C PROCEDURE:
C >	The SEE ALSO list may not be complete
C >	The 'loc' function is used to retrieve the starting address of the
C	arrays. This is an intrinsic function in VMS Fortran. So far all
C	other compilers we've used support this also: Absoft Fortran, Sun Unix and
C	Linux G77 (sometimes after displaying a warning message).
C >	The source and destination can be identical or can overlap.
C	The only exception are the functions involving two source arrays and
C	one destination array, which can produce erroneous results if all three
C	arrays overlap (see discussion for href=ArrayLoc3=). If this occurs, a
C	warning message is displayed.
C >	The 'loc' function and the subroutines href=ArrayLoc2= and href=ArrayLoc3= are
C	used to determine the relative location of the source and destination
C	arrays in memory. The relative location determines whether arrays
C	are processed forward (I=1,N,1) or backward (I=N,1,-1).
C >	Arrays are declared internally as one dimensional arrays.
C	Multi-dimensional arrays can be processed by setting N to the total
C	number of all elements in the array (product of all dimensions).
C
C >	For almost all of the subroutines specifying a negative array size
C	results in checking for bad value (href=BadI4=() for integer, href=BadR4=() for
C	real arrays. 'Bad' array elements are not processed
C	(the main exceptions are the initialization routines).
