FILUM
File Utilities


FILUM is a FORTRAN90 library which can work with information in text files.

Licensing:

The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.

Languages:

FILUM is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a Mathematica version and a MATLAB version and a Python version.

Related Data and Programs:

F90_FILES, programs which illustrate the use of files in the FORTRAN90 language.

FILE_MERGE, a FORTRAN90 program which merges two sorted files.

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

FILE_ROW_REVERSE, a FORTRAN90 program which makes a copy of a file with the lines ("rows") in reverse order.

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

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

Examples and Tests:

Files used for some of the tests include:

DATA_***.TXT is a short sequence of three files, each having 8 data items, 3 on the first line, 3 on the second, and 2 on the third line, to be examined by FILE_SEQUENCE_SIZE.
