From: dmurdoch@mast.queensu.ca (Duncan Murdoch)>How can I access double-dimentional arrays in Pascal using asm? My array>is declared like this: var myarray:array[0..5] of array[0..5] of byte.
You need to do the addressing yourself. For example, to load myarray[i,j]
into AH, do the following:
}
mov ax, i
mov bx, 6 { The size of a row of your array }
mul bx { Now ax holds the offset to element myarray[i,0] }
add ax,j { now it holds the offset to element myarray[i,j] }
mov bx,ax { Put the offset in BX. }
mov ah,myarray[bx] { Load the byte at the calculated offset }
{
This is untested, but it looks okay to me...
