Fortran 90 array allocation

  1. Nov 20, 2012 #1
    Hello forum,

    I was wondering if there is a way to declare/define arrays depending on some previously defined variable.

    example:

    if a=2, then declare/define 2 arrays
    if a=3, then declare/define 3 arrays

    If doable, how does one assign names to these arrays?

    what you can do is declared all 3 arrays as "allocatable", then, depending on a=2 or a=3, you go ahead and allocate as necessary.

    please read up on "allocatable" and take a shot at some Fortran code. Hint: it's very, very simple.
