Hi NG
I have a ugly problem with "String to long"
I cant see ho to makes any long strings...
I have EAGLE 3D to display designed prints. I have the standard installation 
windows.

the pov file look like this:
#local lgt1_pos_x = 0;
#local lgt1_pos_y = 0;
#local lgt1_pos_z = 0;
#local lgt1_intense =

If you need those really huge numbers you can use scientific notation

#local lgt1_intense = 17976900000000001e293;

(I think it's e293. I might have lost count)

Hi all
I have found the error

When i use a EAGLE PCB tu make a prov, the dimension of the board was not 
set.
any more errors into the pov file.

I think it is an error from eagle 3D to pov converter!
I will publish this on to the Eagle newsgroup.

Thankyou all for help.

i don't think that any PC can deal with values THAT large! The FPU just can't deal
with that.

The FPU might not deal with that, but POV-Ray will quite happily parse
scene files that use such numbers. I did check that the POV parser
accepts the line
  #local lgt1_intense = 17976900000000001e293;
before I posted and the scene runs normally. I didn't ask POV to
actually do any arithmetic with the value, that would probably fail
depending on the details of that arithmetic. 

E.g. str(lgt1_intense,-1,-1) returns "1.#INF00"
