neither PALETTE or OUT seems to do anything. This is the code that I am using
OPEN "pal.txt" FOR INPUT AS #1
'OUT &H3C7,0: OUT &H3C8, 0
FOR a = 0 TO 255
INPUT #1, R
INPUT #1, G
INPUT #1, B
PALETTE a, (b\4*65535 + g\4*256 + r\4)
'OUT &H3C9, R\4
'OUT &H3C9, G\4
'OUT &H3C9, B\4
NEXT
CLOSE
The OUTs were code that I was originally using in Qbasic, and they worked fine. I read that FreeBASIC has some bugs in OUT, so I tried PALETTE. Neither OUT or PALETTE seem to do anything to the palette.
f you play a Microsoft CD backwards you can hear demonic voices. The scary part is that if you play it forwards it installs Windows.

Are R, G and B Integers? (I mean 32 bits integers)

Have you used the SCREEN command before setting the palette?

Ok, that solved it a little bit. I also changed all of the values so that I don't divide by four anymore. But now I am getting a strange problem. r, g, and b are equal for part of the palette, in other words, shades of grey. They turn out blue here. In fact, the entire thing it blueshifted. What is causeing this and how do I fix it?
Exact code:
SCREEN 13,,2,1
OPEN "pal.vga" FOR INPUT AS #1
FOR a = 0 TO 255
INPUT #1, r
INPUT #1, g
INPUT #1, b
locate 1:print r,g,b:sleep
PALETTE a,(b * 65535 + g * 256 + r)
line(a,0)-(a,100),a
NEXT
CLOSE
sleep

Your blue element should be * 65536, not 65535. There's your first mistake.
I'd knock on wood, but my desk is particle board.
