You can enter an expression such as 2+3 instead of print*,2+3. You don’t need an end program foo statement to have a script run. You can redefine a function. Here are some thoughts on how it should work. I wonder what others think. Currently you must declare variables before using them. For interactive use, I suggest that LFortran…

discussed making call optional and other syntax changes that could convenient in interactive mode. It’s OK to experiment as long as actual source files that are saved are proper Fortran.
