Re: [Kidbasic-devel] File access?

[Ferry H. <fer...@gm...>]

I definitely agree that we want to avoid the classic basic approach.

The FOPEN (and others) approach is reasonable and we should probably
be working at the character level, as dealing with UTF-8 etc would be
a real pain...

We could take a C-like approach and have a gets(number) function? e.g.
returns <number> characters in a string from the currently open file
(until end of line?)

Hmm.. also, do we want to support one open file or more than one?

Cheers
