The program works with matrices and ptr_arr stores the offsets of the first row.
In bx there is an offset that I want to move to min_i and max_i, but the program does not compile. Compiler writes error a2023 instruction operand must have size.
I tried using mov [min_i],WORD ptr bx, but in debug is looks like mov [bp - 2],bx without dereference for bxwhich I need.
Is it possible to do this in 1 line without transferring bx to the buffer and reading from there.
I'm using masm for ms-dos. Compiling with masm+link in dosbox.
In asm isn't possible to copy from memory to memory(from pointer to pointer) in one instruction. More info here x86 Assembly pointers
