The code ReadGLA12_v4.0.f95 compiled correctly using G95 compiler and can be compiled by ivf +vs2008. but using IVF compiler in cmd:

ifort /stand:f95 /convert:big_endian ReadGLA12_v4.0.f95 /exe:ReadGLA12_v4.0.exe

.f95 is a non-standard file type that is not recognized by the ifort command. Please rename the file to .f90. If you want to use non-standard file types, you can use /source:ReadGLA12_v4.0.f95 to tell the ifort driver that this is a Fortran source file. You will also need to add /free to tell it that it is free-form source.

It is, in my view, a mistake to use the file type to distinguish among Fortran standards revisions. The industry adopted .f90 to mean "free-form source" but many people then assumed it really meant "Fortrtan 90" specifically.
