VBA for loop with negative step, k, calling array(k+1). What will it do?

Question

For k = kT To 0 Step -1
ThKC(k + 1) = ThKCl
.
.
.
next k

Suppose I have kT as 5000. ThkCl is a constant value. During the first iteration when I say (k+1), what will be the index of ThKC array?

I have no idea about VBA and need a script changed to python. So I'm just looking for the logic in the script. I also have the same script in Fortran90 too, but VBA seemed easier to understand. Any tips on the migration are also welcome.

Answer 1

Just guessing, that what you have in mind could be:

kT = 5000

For k = kT To 0 Step -1
    ThKC(k) = ThKCl
    ' Do other tasks.
Next

That would loop from 5000 to 0.
