<sect1>DOS 3.3 Limitations<p>
Although the standard binaries generated by the linker for the Apple&nbsp;&rsqb;&lsqb;
generally run both on DOS 3.3 (with Applesoft BASIC) and on ProDOS 8 (with
BASIC.SYSTEM) there are some limitations for DOS 3.3:
<descrip>
<tag>Disk File I/O</tag>
There's no disk file I/O support. Any attempt to use it yields an error with
<tt/errno/ set to <tt/ENOSYS/. This implicitly means that loadable drivers
are in general not functional as they depend on disk file I/O. However they
may be converted to statically linked drivers using the co65 object-file
converter.
<tag>Interrupts</tag>
There's no <tt/interruptor/ support. Any attempt to use it yields the message
'FAILED TO ALLOC INTERRUPT' on program startup. This implicitly means that
<tt/a2.stdmou.mou/ and <tt/a2.ssc.ser/ are not functional as they depend on
interrupts.

<sect>Problems and workarounds<label id="problems"><p>
Older versions of VICE had several problems with labels. However, even those
versions were still tremendously useful, and all known problems are gone in
current versions. So, here is a list of the problems known to me as of version
0.16.1:
<itemize>
<item>The "<tt/ll/" command does not work. Worse, it seems that internal
memory gets corrupted when using this command, so VICE will crash after use.
Use the "<tt/pb/" command to load the label file in this case.
<item>VICE will crash if you use a label that is undefined. This is probably
the worst problem of all, since it needs just one typo to kill VICE. So, watch
your steps:-)
<item>Cheap labels, that is, labels starting with '@' or '?' are not accepted.
<item>The disassembly output is somewhat suboptimal. However, most things are
just cosmetical, e.g. labels appended to the right side of the disassembled
code.
</itemize>
<bf>Note</bf>: All these problems are fixed in current (&gt;= 1.0) VICE
versions. If you're really using such an old version, you should think about
an upgrade.
