A commonly seen application is that let the program to count the number of data items as will be shown in examples below. However, with IOSTAT=, you can catch this end-of-file mark and do something about it. If your program tries to read passing this point, this is an error. Once you hit Ctrl-D, the system would consider your input stop at there. I'd suggest doing the following also, in case there are more than 2000 records in your file: DO WHILE(1.EQ.1) READ(file1,EOF=200) WRITE(file2) blah,x,blah,y END DO 200 CONTINUE Hope this helps !ДЇAQ in Fortran Wiki, sorry to ask such an inane question but i've left my fortran book back at home I'd like to DO i=1,2000 READ(file1) x,y WRITE(file2) blah,x,blah If you prepare the input using keyboard, hiting the Ctrl-D key would generate the end-of-mark under UNIX. Based on I believe there is an EOF parameter you can put on the read statement where you can define a label of where to jump. Handling End-of-File: the READ Statement Revisited, After executing the above READ statement, the Fortran compiler will put an integer value into the integer variable following IOSTAT=, IOstatus above.

Unexpected End of File in FORTRAN?, Here's what my compiler says: > nagfor -C=all -C=undefined readGAMBIT.f90 &. If you prepare the input using keyboard, hiting the Ctrl-D key would generate the end-of-mark under UNIX. Based on If you try to read passing this mark, it is considered as an error. READ until end-of-line, After executing the above READ statement, the Fortran compiler will put an integer value into the integer variable following IOSTAT=, IOstatus above. In your subroutine, you open the file again, under the same unit.

Actually, you'll probably want to read(9, '(A)') because you want to read the whole line, not just until the first element separator (i.e. It will keep reading records until the I/O list is full. If the format specifier is '(A)', a blank string is substituted to the character variable.'ДЇAQ in Fortran Wiki, Don't use list-directed input. Fortran read statement reading beyond an end of line, From Fortran 2008 standard draft: List-directed input/output allows data editing according to the type of the list item instead of by a format If the format specifier is an asterisk (*), it continues to read the subsequent lines until a non-blank line is found.
