Invalid ASM instruction: "MOV _bckA,A" ???

[LQd]

Please, can anyone tell me, what problem is here?

Code: Select all

module RL_RR

Sub procedure rot_left (dim byref byte_to_rot as byte)
Sub procedure rot_right (dim byref byte_to_rot as byte)

implements

Sub procedure rot_left (dim byref byte_to_rot as byte)
dim bckA as byte
   asm
     MOV _bckA,A
     MOV A,_byte_to_rot
     RL A
     MOV _byte_to_rot,A
     MOV A,_bckA
   end asm
end sub

Sub procedure rot_right (dim byref byte_to_rot as byte)
dim bckA as byte
   asm
     MOV _bckA, A
     MOV A, _byte_to_rot
     RR A
     MOV _byte_to_rot,A
     MOV A, _bckA
   end asm
end sub

end.

I'm trying to write module for rotating bytes in asm, because I did not find anything in MB Pro, but I just can not get through MOV instruction, no matter what I am moving where. Please help. Thanks in advance.
