Correct -- they're executing interpretively which, by definition, is
slow. I'd add any variant of "basic" to that list, too, except for the
few basic that actually compile machine code (e.g., one that I wrote
and another that I have on my 3B1 systems.

speed. But see below for an exception, one of my languages.

but if it's going into "production" usage then the implementation
language choice is very important.
I've designed and written many commercial compilers over the years
which have been used by the US government and military and Fortune
1000 companies. Most of those were integrated into DBMS systems that
I also authored and sold to the same clients, and they generated hard
machine code for even simple queries (e.g., "if A > B") and extremely
complex (and portable) programs 1000s of lines long.
I came up with a new idea generating Machine Independent Code (MIC)
and all tests I've run so far show it to be in many cases faster than
hand-coded assembly language. The MIC is also immediately portable
to numerous hardware platforms (big-/little-endian, fixed or variable
word sizes, etc.) and I'm still working on this concept just to keep
A little while back I posted several previews of how the above works;
see the following for examples:

The 25-June-2011 article shows more detail. I've already compiled
programs of 10,000+ lines in this language and compared them to C
equivalents and the runtimes are very close. I've even written a
hangman game in this language and it works fine. :-)
Note: a fixed-width font is necessary to view the above 2 articles;
I'll post a "howto" later today (didn't have time last night).
I'm still working on the system but I haven't given it the priority
it deserves. I thought I'd have more time now that I'm "retired" but
I'm discovering that's not the case since I have so many interests
and there's only 24 hours in each day and even I do need to get some
sleep occasionally. :-)
