Subject: Tiny scheme with floats ?
Date: 
Message-ID: <37rnk2$8ak@netnews.alf.dec.com>
I'm trying to find a small lisp with floats that is portable to
unix and ms-dos that will run in 512K.  Any ideas ?

I can build siod 3.0 okay, but is too memory hungry to run in a
512K HP95 (where the 8086/8 build is probably killing me because
of the 64k segments instead of the memory, although I'm building
large mode overlaid).  One alternative may be to scrap some things 
inside of siod to regain memory.

I can build various scm versions, but 4c0 for example has a ~175K
executable overlaid with turbo c++ and is too big.  Something like
scm 2b is small enough, but only has 30-bit ints and no floats.
I'm going to dig version 2e out of my library and try that.

Somebody sent me a mini scheme by Atsushi Moriwaki, which is great
size-wise but only has 32-bit integers.

I'm trying to do calculations for ~30 Gbyte database parameters and
32-bit integers aren't enough, and since I don't have 64-bit integers
on some ms-dos compilers or workstation environments that isn't the
solution either.  My goal is to usually run this software on a
workstation or mainframe, but also be able to do it on a palmtop I
can afford (I have an hp95lx).  If I can get closer I can always go
pcmia card and dedicate all of the system memory to the scheme (I
am closest to this with siod 3.0).

Any ideas are appreciated.
