How to move byte into al

[benco5000]

Trying to do some basic assembler
for brevity, please assume that:
*lPointer is a valid pointer to some data, i.e.
'ABCDEFG'

Code: Select all

start:   MOV al, $00             ;; clear register for grins
         MOV al, [*lPointer]     ;; how do I get the character 'A' loaded into the register al?

Something like the following I guess :

Code: Select all

start:   MOV al, $00             ;; clear register for grins
         MOV ebp, dword [p_lPointer]
         MOV al, [ebp]

No need to clear the register. Only if you want to be sure that the whole eax or rax register is clear.
But the mov al,$00 is just unneeded.
