Do you have familiarity with any high level language like C or PASCAL? Passing parameters is how you convey information to subroutines.

Code:
test1(123, 456); // Parameter#1 123, Parameter#2 456
test1(654, 321);


68K equivalent using registers to pass parameter to a subroutine.

Code:
 MOVE.W #123,D0 ; Parameter#1, First Call
 MOVE.W #456,D1 ; Parameter#2
 BSR  test1

 MOVE.W #654,D0 ; Parameter#1, Second Call
 MOVE.W #321,D1 ; Parameter#2
 BSR  test1
