My code as is non functional but I need it to display all registers and flags. INCLUDE asmlib.inc
.data
registerNames BYTE "EAX: ",0, "EBX: ",0, "ECX:", 0, "EDX: ",0, "ESI: ",0, "EDI: ",0, "EBP: ",0, "ESP: ",0, "EIP: ",0, "EFL: ",0
eflags DWORD ?
.code
ShowFlag MACRO flagName, shiftCount
LOCAL flagStr, flagVal, L1
.data
flagStr BYTE " &flagName=",0
flagVal BYTE ?,0
.code
push eax
push edx
mov eax, eflags
mov flagVal, '1'
shr eax, shiftCount
jc L1
mov flagVal, '0'
L1:
mov edx, OFFSET flagStr
call writeString
mov edx, OFFSET flagVal
call writeString
pop edx
pop eax
ENDM
Tab MACRO

mov al,09h
