I have a program that reads a file of birthdays and prints
out impending ones when I activate my (Linux) console.
It first prints a header

print '(/" Birthdays:")'

Is it possible to get it to print that in bold or a colour?
If yes, how?

Ok, I'll bite. So what is the device that you are printing to ?

If the device is a screen then there are control codes that you must
print also.

If the device is a file then, no way. This is the reason that HTML was invented.

Or rather, there are quite a number of ways, depending on how
the file is interpreted afterwards.

Writing HTML to a file and then loading it into a browser is certainly
one way. One thing I someitmes do to write out PostScript from
a Fortran program, where you could use setgrbcolor.

Or you can write out Markdown and insert HTML color.

Or you can...

It's to the console screen.

Maybe this way?

bold.f90: ------------------------------------------------------------------------ program testbold
call system('tput bold')
print'("Hello, World!")'
call system('tput sgr0')
print'("Bye, World!")'
end program testbold ------------------------------------------------------------------------

That's my 1st hand full of Fortran lines since the early 90s, so please
don't laugh too loud.

Using `system` and `tput` avoids needing
+ to find a Fortran (n)curses library
+ to hardcode the terminal commands
.

It worked for me with Gfortran on OpenBSD. I was too lazy to install
Gfortran on Linux while already having access to it on BSD.

Thank you Yeti, that works! You have solved my problem.
