The discussion focuses on creating a Fortran 90 program to process output files named in a sequential format (file.datA, file.datB, etc.). The user aims to implement a loop that modifies the filename by appending letters A-Z to a base string "file.dat". A suggested solution involves defining a new character variable that concatenates the base filename with the appropriate suffix using the TRIM function to manage spaces effectively.
PREREQUISITESFortran developers, computational scientists, and anyone involved in processing output files in scientific computing environments.

I set the variable "file" to equal file.dat. I want the program to run through a loop and each time change the name of "file". Basically I need to add A-Z on the end each time it reads the file.
