If you are working with integer (if not, think of the index of your
float/text/object in an array), I have a set of function that might
interest you... it will return all possible combination between the
values of different variables.
ex: var1= 1 or 2 or 3
var2 = 4 or 5
var3 = 6
will return
1,4,6
1,5,6
2,4,6
2,5,6
3,4,6
3,5,6
now, if you have many possible value, it might be easier to vary the
value "on the fly"...
for var1=0,10 do begin
for var2=12.2,12.4,0.01 do begin
etc
