Not implemented[edit]
These are currently not implemented in Seed7. Please implement some if you can. If any tasks are not possible or too complex in Seed7, they should not be on this list. To mark a task as such, add {{omit from|Seed7}}, preserving the capitalization of the language, to that task. It will appear below under the "Not Considered" section.

Draft tasks without implementation[edit]
These tasks are drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in Seed7 (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[edit]
Examples[edit]
These tasks have implementations in Seed7, 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.
No pages found.
Other pages[edit]
These are other pages related to Seed7 which require attention; with your knowledge and assistance, we can improve the quality of the site's content.
No pages found.
Not Considered[edit]
These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that Seed7 was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.
No pages found.
End of List[edit]
Again, feel free to try your hand at any of the tasks listed on this page.
