I have a Fortran code which reads a "dat" file as shown below:
open(unit=2,file="36_st_18.dat",form="formatted",status="old")
However, sometimes the file name changes ( e.g., x_24_st_42_b.dat). All file names have always 'st' latters in it. How can I generalize the reading in Fortran so that I dont have to change the file name each time. Thanks in advance.
