Get and set Windows Envrionment variable in Fortran

Get and set Windows Envrionment variable in Fortran

Imagen de sommersohn

Hello everybody,

I have a very simple question:
How can I get and set system environment-variables by a fortran
program?
E.g. I want to see if %LIB% and %PATH% are set correctly.

I am using the Intel Fortran compiler.

Best regards,
Michael

Hello

See SETNVQQ and GETENVQQ functions but they can only affect the environment variables of the current process.

Refer to the IVF help for more information.

Windows API functions SetEnvironmentVariable and GetEnvironmentVariable are an alternative.

I think that compiler/linker variables are set only for the related process and are not visible for an external process.

Fortran 2003 defines GET_ENVIRONMENT_VARIABLE, which current Intel Fortran supports, but there is not yet a standard intrinsic to set an environment variable.

LIB is only appropriate for linking, as noted.

Thanks for your help.
GETENVQQ helped me.
Nice forum.
