I am looking for some guidence in writing a fortran program which reads
an external file (one page consisting of text and numbers) and
printing the same file (with different name) with some edits.
Can this be done in fortran 90/95? Help appriciated,
Yes it can, however, depending what you want to change and how the text
and numbers are saved, you should better use another programming
language. Especially for heavy string modifications, I think, other
languages are better suited, even though it can be done in Fortran.
Could you give an example (or explain in more details) how a line in
your file looks like and how you want to modify it? Then we can give
you tips how to do it in Fortran. (And/or to advise you not to do it in
Fortran.)

Tobias,
Thank you for your response.
My file looks like this; I will have to change some numbers (not text)
and write the file with a different name.
