forrtl: severe (47): write to READONLY file, unit 5, file /dev/pts/1

hello all,
i am trying to program using intel's fortran compiler 9.0 for linux. I was able to compile successfully my program and it produced a file a.out. When I tried to run a.out the below error occurs. I have no idea what that below is talking about. Online has given a description of what it is but doesn't tell of finding a solution to the problem. Pleae let me know what you guys think. Thanks so much.

/dev/pts/1 is your "terminal window". It should generally have permissions like this (allowing you - and only you - to read from it and write to it):

ls -l /dev/pts/1
crw------- 1 paulsm tty 136, 1 2005-10-01 20:14 /dev/pts/1
So it sounds like you're trying to do a FORTRAN "write(*,*)" to FORTRAN unit 5, and the system isn't letting you (e.g. you don't have write permission).

Please try this:

1. Be sure you're running "a.out" as the same user you're logged in as.

2. Run the command "ls -l /dev/pts" and verify a) that /dev/pts/1 actually exists, b) that it's owned by you, and c) that it has both "r" (read) and "w" (write) permissions.

'Hope that helps .. PSM
