I assume that new menu's are inserted before Tab menu in DrRacket.

Is it possible to insert a menu between two other menu in menu-bar but
not at the end?
More specifically if I want to add a new menu in DrRacket between
"Racket" and "Insert" how do I do that?
Thanks

In racket you are applying function "base64-encode" and in python you are not.
Sorry if I didn't get your question.

Hello ,
How do I during compilation stop propagation of shared state in a some

Why macro call (phases) produces '(1 0) and not '(1 2) ?
(module mod1 racket
(require (for-syntax syntax/parse))
;"mod-compile.rkt"))
(require (for-syntax
(for-syntax syntax/parse racket )))

(provide set-compile phases)
I think the conflict may be here(I may be wrong) :
When parser encounter C , it can reduce to y or it can shift i.e it think
there is A waiting to be read, hence shift/reduce conflict

Since server part expects escaped data based on rfc 1738 , I "assume"
