Hi to all !

A stupid problem , i write an array and i can't read it (141 vectors) with a
'while loop', here's the console message :
--
File: _array.inc  Line: 43
File Context (5 lines):
<462.75,1,102.5> ,<462.75,1,102.5> ,<462.75,1,102.5> ,<493.5,1,101.25> ,
<
Parse Error: No matching } in '{', < found instead
--

In  this  file  _array.inc i see nothing wrong; here is end lines :

<462.75,1,102.5> ,<462.75,1,102.5> ,<462.75,1,102.5> ,<493.5,1,101.25> ,
<511,1,101.5> ,}

And my while loop is :

#declare I=0;
#while (I <Nbr_de_pt)
sphere{Traject_array[I],5 pigment{Blue}}
#declare I =I+1;
#end

I really don't know and see where, and what is the mistake. What do you think
about ?
Thanks for your interest about this.

There is a coma before the closing brace.
As it is now, you write eache elements and unconditionaly follow it with 
a coma, resulting in one superflous coma.


Possible cure:
Write the first element.
Write a coma BEFORE each successive elements.

or, if you use a counter when writing away your data:

         //Writing the last line in the file:
         #if (i = Count)
           #write (MyFile,MyValue,"\n")
         #else
           #write (MyFile,MyValue,",\n")
         #end

But I guess that Alain's solution is faster.

Hi,

<462.75,1,102.5> ,
<462.75,1,102.5> ,
<462.75,1,102.5> ,
<493.5,1,101.25> ,

<511,1,101.5> ,
}

and i've got same problem..

Well, again, the last comma should be deleted in any case. Maybe your 
array declaration is in error.

You could try also the solution explained in the message above "Reading 
from a text file" and see if the error is still there.

what's the entire statement? If you write this
file for "#including" it should have the form of

#declare Traject_array = array[<number of elements>]
{
   <462.75,1,102.5>,
   ...
   <511,1,101.5>
}

Hi,

It's OK , i've got it!!!!!!!!

So tired, i forget the real number of element [] about just one vector. The
message console trouble me ...

Thanks for all, and happy new year !!!

Hi,

so i try to convert a spline to an array 1 dimension

heres is the macro i write and use for it, maybe it'll better for other multiple
dimension...



//  convert_spline_array.mcr
// eg:
//      #include "convert_spline_array.mcr"
//
//
Convert_spline_array(Traject_Spline,0,141,"circuit_array.inc","Traject_array")
//
//That's it ! It's always a little step ...

#macro Convert_spline_array(spline_name, first_pt, last_pt, output_file_name,
output_array_name)


   #declare Nbr_de_points =(last_pt-first_pt)+1;

  #fopen Data output_file_name write

        #write (Data,"\n\n")
        #write (Data,"// ",output_file_name,"  \n\n")
        #write (Data, "// A convert  Spline() to array [] made with
convert_spline_array.mcr\n")
        #write (Data, "// Author : Albun  //Date:  13/01/2012 \n\n\n")
        #write (Data, "// \n")
        #write (Data, "//  \n\n\n")

        #write (Data,"#declare ",output_array_name," = array[",Nbr_de_points,"]
{\n")  //array initialization

                #declare V=first_pt;
                #while (V<= last_pt)

        #write (Data,spline_name(V))                   // array pts
        #write (Data,", //     ",V,"\n")               // nbr of the spline pt

        #if (mod(V,4)=0 ) #write (Data, "\n") #end     // write 4 pts by 4 pts

                #declare V=V+1;
        #end

         #write (Data,"}\n")

 #fclose Data


#end //of macro convert_spline_array.mcr



Bye !
