Intel Fortran Compiler, Ifort.
The CodeThe following MWE describes what I want to use (note that I did not design this, I am merely trying to use someones code, I would not usually use global variables). PROGRAM MAINIMPLICIT NONEinteger:: Nreal(8), allocatable:: a(:,:)N=3allocate(a(N,3))a=initializearrayCONTAINSfunction initializearray result(a)IMPLICIT NONEreal(8):: a(N,3)a=1end function initializearrayEND PROGRAM MAINThe Problemgfortran gives an error which reads Error: Variable 'n' cannot appear in the expression at (1), pointing to to the real(8):: a(N,3) inside the function.In a subroutine it would work, so what might be the problem here?

15.0.3) compile this, while gfortran (v. 4.8.4) does not? I think this might be an explanation, though like @VladimirF I can't actually either recall or find the relevant section (if there is one) of the standard.This line real(8):: a(N,3)declares that the result of the function is an array called a.
This masks the possibility of the same name referring to the array a by host association. The a inside the function scope is not the a in the program scope.The declaration of an array with a dimension dependent on the value of a variable, such as a(N,3), requires that the value of the variable be known (or at least knowable) at compile time. In this case giving n in the host scope the attribute parameter fixes the problem. Though it doesn't fix the poor design - but OP's hands seem tied on that point.It doesn't surprise me that the Intel compiler compiles this, it compiles all sorts of oddities that its ancestors have compiled over the years for the sake of backwards compatibility.I only offer this half-baked explanation because experience has taught me that as soon as I do one of the real Fortran experts (IanH, francescalus, (usually) VladimirF) will get so outraged as to post a correction and we'll all learn something.

Visual Studio apparently was a 30 day trial rather than a full installation (it's expired now and will launch and function for a short time before a popup freezes the program and asks me to buy a license or exit Visual Studio), so that may have something to do with this error. Looking at the output, it looks like it finds the IFORTCOMPILER19 environment variable, the ifort executable, and a registry setting, but it fails on a command to echo the vcroot environment variable. The problem seems to be that C:Program Files (x86)Microsoft Visual Studio2017CommunityVCAuxiliaryBuild doesn't exist; everything up to 'Build' does, but Auxiliary only contains a folder called VS for me. Is there a way to get around this?
