[comp.sys.ibm.pc] PC LISPs

leverich@randvax.UUCP (Brian Leverich) (02/25/88)

I'm interested in receiving comments from anyone who has actual hands-on
experience with LISPs that run under MS-DOS on PCs.  I'm particularly
interested in:
   * The speed of the compiled code at number-crunching (Does the
     LISP have some reasonable internal representation of real numbers?
     Does it know how to use a math coprocessor?  Etc.)
   * The size of the data spaces (atom, dotted-pair, number, string, etc.)
   * How flexible is file I/O (Can you open a file direct access R/W?
     Can you write numbers to files in their internal representation, or
     do you have to do a conversion to an ASCII representation?  Etc.)
Vendors' glossy literature tends to gloss right over these little details,
and hands-on experience seems to be the only way you really learn about
them.  :-(

I have essentially no interest in the usual AI weenie concerns with the
look and feel of the development environment.  Structure editors are for
wimps who can't count both forwards and backwards.  :-)

(Given the foregoing, it may sound like I need an innovative new language
called FORTRAN.  Actually, I'm an old FORTRAN hack but I just can't make
object oriented simulations happen without manipulating mountains of list
structures.  And that's sooo painful in FORTRAN...)

Thanks for any help anyone can give me.  -B
