pipe screen output to file

[Maughan__Justin]

i am fairly new to fortran and am using an existing code it opens a file using

 OPEN (6,FILE='outdata')

it is my understand that 6 is reserved for printing to screen and so this works to direct anything printed to screen to the outdata file and it works when i use gfortran for example 

but when i use ifort it does not is there any simple way for me to fix this with out going through the entire code and changing every print statement (there are many of them)

No, this open discards preconnection to screen.,  then it goes directly to the file.

Unit 6 is not "reserved", but it is "preconnected". The difference is probably if you also use PRINT or WRITE to unit * - by default these don't use unit 6. The easy solution is to compile with the switch -standard-semantics . This implies -assume noold_unit_star and will get the behavior you want.
