How do i 'relabel' variables (in fortran)

[tothetop]

Suppose I have a global variable like "GauntCoefficients".. and I want to use it in a formula in the next block of code. In C++, I might do something like this to make the code more readable:

const int* gc = GauntCoefficients;
(then write some nasty formula with "gc" rather than "GauntCoefficients" everywhere)

Since "gc" is declared here as a constant, the compiler should just delete it (I think). And since "gc" id declared locally.. it doesn't pollute the namespace.

Can I do something like that in Fortran?

Hey
In Fortran 90 and newer pointers are possible to use. But they are more restrictive than in e.g. C/C++.
You can therefore do something like this:

integer, target::GauntCoefficients
integer, pointer::gc
gc=>GauntCoefficients

I hope this helps.
