TASM Error

Hi :)

I am learning and i am getting an "Illegal Instruction Error" from TASM compiler. What does it mean?

Code:

---

text        segment
assume        CS:text,DS:data

VirtualReplace proc ptrString ;pass parameters
        ;looping...
        mov SI,0
        mov CX,2

scroll: ;we are scrolling
        inc SI ;increase counter...
        mov ptrString[SI], 30       
        loop scroll         
endp

begin:
  mov AX,data ;create data segment
  mov DS,AX  ;move AX to DX
  ;This is where the error happends
  VirtualReplace ptr offset hello
  mov AH,09h  ;screen output
  lea DX,hello ;move output
  int 21h    ;call dos
  mov AH,4Ch  ;finished!
  mov AL,0    ;code 0 - success
  int 21h    ;call dos
text  ends
data        segment
symbols db 233 dup('*')
crlf      db 10,13,'$'
hello  db 'hi!$'
data        ends
stk        segment stack
        db 256 dup (0)
stk ends
        end        begin

Can you call a function this way in TASM?
Usually you push the arguments on the stack, then do a 'call'.
MASM has the 'Invoke' high command to make things a little easier.

Thanks for your reply :)

You can call macro's this way, i dont know abut functions.
I'l try the push method
