program maine5
real :: x(2,2), z(2,2)
OPEN(11, File="output4.txt",STATUS='REPLACE')
data x /1,2,3,4/
z =x
z = matmul(x,x)
write (11,'(f5.2)') z
write (*,'(f5.2)') z
close(11)
end program maine5
This turns into a runtime error for me. If I comment out the matmul statement, it runs fine. The fellas at c.l.f. suspect my IDE (Plato 3) and my settings, on which I'm vague. Ideas?

I cannot get this program to fail.
I have tried all kinds of command line options and so far it works every time.

I am using the latest version of FTN95 and running on Windows XP.

Try running from a command line....

FTN95 prog.f90 /lgo

Success!

Off the command line, I type
FTN95 maine5.f95 /lgo
and get correct output:
7
10
15
22

What's that mean?

I don't know what is going wrong.

What Plato does for you is something like the commands...

FTN95 maine5.f95 /link
maine5.exe

You could try reinstalling everything.
Plato3.exe, FTN95.exe and salflibc.dll should end up in the same folder.
