===Bugs===
A deficiency with error-trapping via <code>ONERR</code> means that the system stack is not reset if an error-handling routine does not invoke <code>RESUME</code>, potentially leading to a crash.<ref name="ManualIIe">{{cite book |title = Applesoft BASIC Programmer's Reference Manual (for IIe only) |url = https://archive.org/details/applesoft-basic-programmers-reference-manual-vol-1-for-iie-only/page/70/mode/2up |publisher = Apple Computer, Inc. |year = 1982 |page = 70 }}</ref> The built-in pseudorandom number generator function <code>RND</code> is capable of producing a predictable series of outputs due to the manner in which the generator is seeded when first powering on. This behavior is contrary to how Apple's documentation describes the function.<ref>{{cite journal |last1 = Aldridge |first1 = James W. |title = Cautions regarding random number generation on the Apple II |journal = Behavior Research Methods, Instruments, & Computers |date = July 1987 |volume = 19 |issue = 4 |pages = 397–99 |doi = 10.3758/BF03202585 |s2cid = 62633043 |doi-access = free }}</ref>
