FILE_MERGE, a FORTRAN90 code which merges two sorted files.

FILE_NAME_SEQUENCE, a FORTRAN90 code which demonstrates ways to generate a sequence of filenames that can be used when generating images for an animation.

FILE_TRANSPOSE, a FORTRAN90 code which makes a "transposed" copy of a file, in which the I-th "word" of the J-th line becomes the J-th word of the I-th line.

FILES_MULTIPLE, a FORTRAN90 code which demonstrates how a code can open multiple output files at one time, and write data to any one specific file it chooses.

filum_test

REFORMAT, a FORTRAN90 code which makes a copy of a file with a given number of "words" per line.
