int iErrorValue = 0;

public void someMethod( ) {

// do someMethod’s stuff here

// if there is an error, then set iErrorValue = 1

}

public void someOtherMethod( ) {

// do someOtherMethod’s stuff here

// if there is an error, then set iErrorValue = 2

}

public void someThirdMethod( ) {

// do someThirdMethod’s stuff here

// if there is an error, then set iErrorValue = 3

}

Another way error handling is to have the value of a global variable represent the error.
