Hi All I have a problem in the work with Fortran90. I have a file that don't have any idea for read it. It consiste of number and character.For example it includes as below 1 15193r 8 9r 4 6 74r,... I want to write these numbers in 2 columns. For example 1 15193 8 9 4 0 6 74 terms with r show the number of iteratin and number ( that after it dosen't exist term with r) shows that this number has no iteration. Please help me. Thanks a lot.
