Bingo! The display format is why my DM15L just kept on running. Should have remembered that is how it derives (no pun intended) its accuracy.

What accuracy and display format did you use when you tested this on the DM42? I just get an "Out of range" error when attempting the integration.

It works fine for me -- my program looks like this:

01 LBL "ECUBE"
02 MVAR "X"
03 RCL "X"
04 3
05 Y^X
06 E^X
07 END

LLIM=0, ULIM=6; for ACC I tried 0 and 1E-12, and the integration works fine with both (though it takes about 26 minutes with ACC=0).
