The uses statement is a declaration by a Pascal program that it will invoke or use certain procedures, functions, objects, constants, variables and other items which are defined or declared in the specified unit.

Every pascal program and unit has an automatic implied uses statement of

except in the case where a compiler parameter allows a unit to exclude a reference to the System unit. (One example of this would be if one was recompiling the System unit, it would be necessary for it not to invoke itself.)
