In this instance, there was only one error. If multiple errors occur, Processing will only alert you to the first one it finds (and presumably, once that error is corrected, the next error will be displayed at run time). This is somewhat of an unfortunate limitation, as it is often useful to have access to an entire list of errors when fixing a program. This is simply one of the trade-offs we get in a simplified environment such as Processing. Our life is made simpler by only having to look at one error at a time, nevertheless we do not have access to a complete list.
this no longer applies
