Subject: Re: Executing part of the code instead of another
Date: Wed, 7 Oct 2020 15:09:26 +0200	[thread overview]
Message-ID: <trinity-064edf7c-a27c-4eb2-b57c-75c657d33355-1602076166887@3c-app-mailcom-bs01> (raw)
In-Reply-To: <m2y2ki8pub.fsf@gmail.com>

I have tried executing the following condition (if (nb > na))

(setq na 2)
(setq nb 5)
( if (> nb na)
    (message "nb > na [condition true]")
    (message "condition false")
)

I highlighted the region then pressed C-x C-e
It returned the first message as expected, but when I tried
the next one, I still got the first message.

(setq na 2)
(setq nb 1)
( if (> nb na)
    (message "nb > na [condition true]")
    (message "condition false")
)
