Is there any way (romcall) to check if there is enough memory free in the archive?
I want to bypass an occasional error generated from Arc_Unarc when archiving an object while there isn't enough room for it.
I usually use _ChkFreeArc, aka bcall($5014), which returns the 32-bit value of the number of free archive bytes.

Thanks a lot, KermMartian!

Sure thing, I hope it helps you! It's definitely a good idea to check free ROM before you archive and free RAM before you unarchive.
I do do a RAM check before creating the AppVar or unarchiving it.
The documentation on _Arc_Unarc said it will throw an error if it can't archive the object you want it to, but I don't get any; it just leaves it unarchived
but when I use _ChkFreeArc before archinving with _Arc_Unarc, sometimes it locks up, so I ended up not using it at all.
Whoa, really? That sounds to me like something else may be wrong, because I don't think I've ever had a problem with lockups.

Must've been an error in my coding. It is working okay now.

I'm curious what the problem was, though.
Too late, I'm afraid. All record of the state of the program at that moment is lost forever...

Oh well, the important thing is that it works now, and this topic still exists for other people who are trying to find out the amount of free archive on their calculator.
