Thanks, that's the way to go.

Thanks. That's important because I do override a few methods. For example,
set-cell! erases pencil marks and clear-cell! puts them back in. But in most
cases the methods are not overridden.

Hi Kieron,
An argb has a vector that we can probably mutate. It also holds width
and height, so
I have a contract
(define base-grid/c
(class/c
(given? (->m coord? coord? boolean?))
(get-cell (->m coord? coord? digit?))
(get-cell/given (->m coord? coord? (values digit? boolean?)))
(set-cell! (->m coord? coord? digit? void?))
(set-given! (->m coord? coord? digit? void?))
(c
Hi all,
Does anyone know how to easily go from a *.ico file (maybe Windows only) to
a bitmap% or something else I can use in program?
I see the function read-icos in file/ico, and also the function ico->argb

how to get fro
I'm not sure what error you're referring to in the second case, unless
you mean that the timeout is shorter than the expected availability of
job A's results, in which case you should expect it to be an error,
because you went over the time limit.
If you used the LRU manager and then combined that
There is char->integer, but it produces the character's number in Unicode,
so #\1 would not map to 1. You may be best off in that case with
(string->number (string ch)) for any character ch.

Is there a similar function for characters? I.e., one that will map #\1 to 1?

The problem is not the length of the query, but a query which
The following expression should do what you want:
(+ (string->number "1.2") 1)
If you're starting from a symbol, use symbol->string before string->number.

Hi all,
In tinyscheme I can do this:

2.2
In racket that does not work, because

2.2

Yes, you are right. define/provide-logger seems like the best way to go.
But a logger-out may still be useful to explicitly re-provide the names,
e.g. if the logger was defined in a 'private' file.
