Hi,

I'm teaching myself Fortran and I compiled my first program. When I went to run the file at the command line I changed to the directory of the file and entered the filename and nothing happened.
After searching a bit I found I had to enter

./<filename>

and not just

<filename>

My question is, what is the significance of using ./ as I thought it just meant the path was relative?
Is just entering the filename of an executable file not valid, even though you're in the directory of the target file?

Thanks.
