Who can help this Fortran problem.

[coolhow]

I have a problem in my programing in Fortran:

First there are some variable pairs like: (a, aa) (b, bb) (c, cc)

and they have a relation like:

a=f(aa)

b=f(bb)

c=f(cc)

The question is: I have a large number of this variable pairs, so I do not want to write this every time.

Can Ihave somethinglike a name group: a, b, c-> group1

aa, bb, cc-> group2

then I only need to write:

group1=f(group2)

Thanks.

I think I would just have an array of pairs:

type Pair

integer :: x

integer :: y

end type Pair

type(Pair), dimension (1:number_of_pairs) :: pairs

!you would put all the pairs in the array somehow

!effectively putting them in a "group"

pairs(1)%x = a

pairs(1)%y = aa

etc...

do i=1, number_of_pairs

pairs(i)%x = f(pairs(i)%y)

Forgive me if they syntax isn't perfect, I'm very new to fortran

No, it's not so simple, because the variables a,b,c are variables used someplaceelse, and theyactualyare allocated arries with different shapes. The point is:these variableshave different names, but they all have very similar operation in someplace, (eg. deallocate them all), and I do not want to write every name of them, if they can be included in a name group and be treated together, that will be nice.
