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

Not implemented[edit]
These are currently not implemented in BASIC. Please implement some if you can. If any tasks are not possible or too complex in BASIC, they should not be on this list. To mark a task as such, add {{omit from|BASIC}}, 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 BASIC (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 BASIC, 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 BASIC which require attention; with your knowledge and assistance, we can improve the quality of the site's content.

Not Considered[edit]
These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that BASIC was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.
End of List[edit]
Again, feel free to try your hand at any of the tasks listed on this page.
