jupemaho AT utu DOT fi (Juha-Pekka Höglund) was overheard mumbling
incoherently about Prob with Allegro RLE sprites / BMP blitting:

>I've got 36 64x64 bitmaps in a array. They load just fine, but when I

DJGPP doesn't distinguish between near and far pointers (FAQ 17.7).
In pascal, an array of 10 integers is normally declared as

var a:array [1..10] of integer;

a[1] is the first element, and a[10] is the last.  In C, you use

int a[10];

a[0] is the first element, and a[9] is the last.  If you try to access
a[10], you get a SIGSEGV.  If that's not your problem, then post your
code.
