I've tried to pinpoint the root of the problem and found that at least the built-in head and tail functions do not work as expected in the Mac Emulator. (Apparently they do in the PC Emulator, cf. the thread above.)

The functions do not seem to work when the parameter is a local variable.

The following program returns {17, 42} on my HW Prime, version 10637, but el on the Mac Emulator Prime, version 11226:

Code:

EXPORT FOO()
BEGIN
  LOCAL el={{17,42},{13,24},{42,1}};
  RETURN head(el);
END;

Calling head on global variables works OK, e.g.

Code:

L0:={17,47111,42};
RETURN head(L0);

returns 17 as expected.

Even more weird, when I start the Emulator from the command line, i.e. do:

Code:

$ /Applications/HP\ Prime.app/Contents/MacOS/HP\ Prime

both the FOO program and my Soduko work as expected, but if I open the emulator by clicking on the icon in the dock, or by:

Code:

$ open /Applications/HP\ Prime.app

FOO returns el as shown above.

At least I now have a workaround.
