Actual Parameters
The actual parameters must fulfill these requirements known as the formal/actual correspondence rules
- There must be the same number of actual parameters in the call, as there are formal parameters in the proc declaration
- The order of the parameters matters --
- The 1st actual parameter corresponds to the 1st formal
- The 2nd actual parameter corresponds to the 2nd formal
- The types of the actuals must match the types of the formals
- Any formal used as a procedure output must have a variable as an actual
