Structures

[Mike B.]

Hi All,

Would appreciate advice how to the following efficiently:
I have two structures A and B.
1. Need to cycle over the fields of A in a particular order.
2. If B has a field with an identical name then A is assigned the content of 
B's field.
3. Evaluate the field in A.

For example (f1 then f2 then f3):
A.f1 = 1    
A.f2 = A.f1 * 2
A.f3 = "abc"

B.f2 = A.f1 *5
B.f3 = "def"

so after looping over A (and given B) the output is
A.f1 = 1
A.f2 = 5
A.f3 = "def"


Cheers,
Mike.
