Program: SUB
Purpose: Subtract one or a series of subsets from another
series of subsets.
Category: COMBINATION

Author: M. Vogelaar
Keywords:
INSET= Input set (and subsets). Maximum number of subsets
is 2048.
BOX= Frame for input subsets: [entire subset]
SETX= Set name and subset(s) which operate on the input set.
SUB subtracts subsets in two different modes:
A: One 'SETX' subset works one all 'SET' subsets
B: All given 'SETX' subsets work pairwise on all
subsets of 'SET'
Depending on the number of user given 'SETX' subsets,
the program selects the mode of operation.
BOXX= The axis sizes of the subset box of 'SET' have to be
equal to the axis sizes of the subset box of 'SETX'.
If using comparable subsets (i.e. same axis names,
same grids and origins), this keyword is hidden.
OUTSET= Output set and subset(s) for the result.
The number of output subsets is the same as the
number of input subsets.
