now in order to call a proc from another file, the files

which contains the proc will have to declare the proc

as public :

.

.

.

public clearscreen

clearscreen proc far

.

.

.

ret

endp

and in your file you will have to declare the proc as extrn :

.

.

.

extrn clearscreen:far

.

.

call clearscreen

you can also declare public/extrn global arguments.

way of compiling :

your file – prog.asm

extrn file – clear.asm

than

tasm prog

tasm clear

tlink prog clear

error can occure in tasm if you didn’t define public/extrn and in tlink

if you wont supply the extrns.

in this point you know most of assembly but you are lacking of technics

in this point you will have to get sources and analize them, in the

next chapter we will talk about entering info into EXE
