I have a very powerful dos based program written in Fortran last updated in +- 2001. The input files for this program must be such that each character must be in a certain position when fed in. If one character or number is out of place it will not work or will give the incorrect output. Is there some kind of software available to more easily enable one to format the text input data?(more easily than what I do now which is use a plain Text editor) Is there perhaps a more advanced text editor that will assist with this matter?
