Hi everyone,

How can I assign a variable name to a character variable in fortran. I would like to make an output file for my program but the name of the file would be changed during running and I need to record all of them. I don't want to repeat whole commands for making the file. If someone knows how it could be happened in fortran, I appreciate to let me know.

Thanks MM

Write the variable to a character string. For example, for an integer n:

write(filename,'(a5,i2.2)')'file-',n

then open(1,file=filename,....)

This will make files called "file-01","file-02", etc.

Is this what you meant?

Thank you so much, it was exactly what I was looking for.
