| Moreover, I found a difference between the behavior of "rpl -i" and
| the behavior of a HP28S calculator: variables which contain programs
| are not spontaneously evalued.

I am used of HP48G(x) and it acts the same way as HP28S ...

this is because the default action is to evaluate variable ( and thus
their content ), by jumping to the address of their content ( the
identifier of all content is in fact the ASM adress of the routine which
can manipulate them, and the manipulation for program is to be run ... )

Since RPL/2 do not run ASM directly, I expect Joel not to be aware of
that, and to push content on the stack for all content without checking
the type of content ...

I did not read source of RPL/2, but the bug you mention makes sense to me.

as you say, RPL/2 remains a very good tool - but full compatibility with
HP calculators would de a plus ^^
