I know that this REPL is sometimes useful, but not for my use case.
I eventually succeeded with (de *Err (bye)).
During this journey, I noticed a few things.

Hi all,
I emulated a «while» loop with a function defined with a `de`, say `my_while`.
It has a body that allows a user defined body (the user is a developer!)
to be executed, thanks to 'run.
Now when the code of the user/dev contains a mistake, the location
of the error is always at the line wher

Hi Alex,
I was staring at this magnificent piece of code, say in this file:

My guess about the «why»: since its an assembler, there is no need for

OK, then the reason why there is no need to quote A in the example at:

is that A is not really n
Hi,
Maybe I should tell my problem as a whole.
I'm implementing a embedded language in PicoLisp.
I'm currently implementing lists with objects:

(dm push> (elt)
(conc (:: elts) (list elt)) ) # this doesn't work

Hi list !
This thread is meant to collect ideas about PilMCU.
At least mine (because I need to clean them up a bit)
and ideas of other PicoLispers (out of curiosity).
Maybe some items will look more like questions like «is it even possible?»!

It really can't hurt. Maybe it could even ×10 (or more) the founds.

Hi,
I was wondering how easy it was to pass floats to java libs from Ersatz,
and also maybe receive some and rescale them to ints.
I can't find anything about this in the docs of Ersatz or in
srborlongan's project:

Hi all crazy Lispers!
I managed to handle "" being NIL, thanks to Michel and Alex.
Now I have another similar problem with numbers.
First, I understand the reasons behind having fixpoint numbers
in Picolisp (basically simple implementation and control).
Now considering that my goal is to implement

Oops. Indeed.
In fact I'm still very influenced by Tcl. Tch has an «interp» command
that allow to create, and in fact cascade, interpreters.

Executing a script doesn't mean every line will work as expected!
