Hi Tom
What I like about it is that you can just use print *, dumbly and it always
provides useful, albeit not beautiful, results. When I'm writing a program,
I use print statements very liberally to observe what's going on - I find
this more convenient than an in-line debugger.
As the last line in my program below shows, it's easy to switch to
formatted output when you want to. The formatting capability is pretty
thorough, I'm just showing a simple example.
This Fortran program doesn't do anything, it just illustrates what the
print statement produces:
real x, y
integer i, j
complex z
character*6 name
x = 2.6
y = -4.
i = 36
j = -40
z = cmplx(17., 19.)
name = 'Larry'
print *, x, y, i, j, z
print *, 'x = ', x, ' and j = ', j
print *, 'Hello, ', name, j
print '(2f8.3, i5)', x, y, j
stop
end
The output is:
2.60000 -4.00000 36 -40
(17.0000, 19.0000)
x = 2.60000 and j = -40
Hello, Larry -40
2.600 -4.000 -40
Is this what you are looking for?
