How to declare a function that returns value and has parameters x86 assembly MASM -

i'm trying declare function using proc , far not work:

inputarray(lpintegerarray:dword,lpstrnum:dword,lpstrprompt:dword):dword proc 

and neither this

inputarray proc lpintegerarray:dword,lpstrnum:dword,lpstrprompt:dword:dword 

how declare function in x86 assembly masm takes parameters and returns dword value?

i'm using .model flat

well, chisx, if astronomy, can tell assembler language planet, different other. next code little 8086 assembler program intel syntax has 1 function calculate factorial, gets 1 parameter si register , returns value in ax register (made emu8086) :

.stack 100h .data .code           ;initialize data segment.   mov  ax,@data   mov  ds,ax    mov  si, 5 ;parameter function.                                            call non_recursive_factorial ;results returns in ax.  ;finish program properly.     mov  ax, 4c00h   int  21h            ;----------------------------------------- ;function calculate factorial. ;parameter : si. ;returns   : ax. proc non_recursive_factorial   mov  cx,2 ;second number multiply.   mov  ax,1 ;first number multiply. while:                                     mul  cx ;ax*cx = dx:ax.   inc  cx ;next number multiply.   cmp  cx, si ;parameter been used.   jbe  while   ret endp 

not sure if looking for. hope helps.
