Apologies for lobbing this request to all you wonderful folk who maintain and
develop GFORTRAN.
Given that you are making noises about Fortran 2018 - and the language is still
alive, kicking and thriving - can you recommend and/or point me at a public
domain GUI that works well with GFORTRAN?
As a Fortran end User I marvel at your ongoing efforts !!
Regards / thanks. Happy Christmas and Best Wishes for (Fortran) 2018.
