forint.sl -- beta version

["Klaus Schmid" <klaus.schmid@xxxxxx>]

forint.sl allows to write formulas (slang) in a text file and
to insert the results on certain places by calling an evaluation
function (forint).

A complete and very simple example:
a) Download forint.zip from http://home.wtal.de/klaus/jed/ ,
    unzip and put it in your Jed library path.
b) In Jed, evalfile("forint.sl")
c) In an empty buffer, type two lines:
% test
a= 1+1 =;
d) M-x forint
Now the buffer looks like
% test
a= 1+1 = 2 ;

A more useful example (buffer already evaluated):

%-*- mode: slang; mode: fold; -*-

% example usage of forint.sl
% NB: use ' =' to indicate 'show current value'
{
   Q= 6.25; l= 2.6; g= 9.8066; ny= 1E-6;
   
   di= 0.54; da= 0.915;
   A= pi/4 *( da^2 -di^2);
   U= pi *( di +da);
   dh= 4 *A /U = 0.322144 ;

   v= Q/A = 14.5846 ;
   Re= v *dh /ny = 4.69835e+006 ;
   lamda= lamda_colwhi( Re, 0.1E-3/dh) = 0.0152055 ;

   v = 14.5846 ; % no assignment but output
   hv= lamda *l /dh *v^2/2/g = 1.33097 ;
}

% tables -- yet not perfect, but it works.

%table: k= (); Re= (); lamda_colwhi( Re, k/dh);

As always, suggestions welcome.
