Awareness

If Fortran is a language you like, or are interested in, please inform your fellow members of the Fortran community; this page can't be emptied without your and their participation.

Not implemented

These are currently not implemented in Fortran. Please implement some if you can. If any tasks are not possible or too complex in Fortran, they should not be on this list. To mark a task as such, add {{omit from|Fortran}}, preserving the capitalization of the language, to that task. It will appear below under the "Not Considered" section.

Draft tasks without implementation

These tasks as drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in Fortran (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of the task itself.

Requiring Attention

Examples

These tasks have implementations in Fortran, but somebody, somewhere, decided that the example implementation was faulty or in some other way requiring attention. If you're familiar with the task and language, please consider reviewing/correcting the example and removing the notice.

Not Considered

These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that Fortran was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.
