I am probably missing something simple, but I am having intermittent problems with Modulo Arithmetic via both the soft keys and when using the ADDTMOD command within a program.

And it is the intermittent part that is driving me crazy.  I'll put two integers on the stack, and then when I try to execute the command, I get a generic, "Bad Argument Type" error condition.

Any suggestions?  Many thanks in advance.
