I would like to be able to switch back and forth from Applesoft to Integer BASIC under ProDOS by typing the commands "INT" and "FP" just like under DOS 3.3, without crashing into the Monitor!  And, I would like to be able to LOAD, RUN, and SAVE Integer BASIC programs under ProDOS to floppy/hard disks (or to disk images in emulators, like AppleWin).

I just downloaded it and it works fine.

I didn't plan for IB to be used at the same time as applesoft due to IB being in lower memory.

If you load and run an applesoft program while IB is in memory, the strings will overwrite IB.

If you know how to use Basic.system's call to $BEF5 to reserve memory between Basic.system and its buffers, then you will have to program it that way and IB will have to be moved into place. 

You can also try setting Himem to $7C00 (31744), to use both basics.

Just type this at the prompt after loading IB and before CALLing 32768 ($8000)

HIMEM: 31744

Also make sure your applesoft programs don't reset Himem.
