For a simple starter project I was putting together a 2-7segement display 00 to 99 counter coded on sketch.
//The line below is the array containing all the binary numbers for the digits on a SSD from 0 to 9
const int number[11] = {0b1000000, 0b1111001, 0b0100100, 0b0110000, 0b0011001, 0b0010010, 0b0000010, 0b1111000, 0b0000000, 0b0010000};
I believe that my solution is either to change this part of the code or add another line, I'm just unsure.
Any advice?
I have tried adding another line to set one of the displays to stop at 6 but it didn't compile with the rest of the code.
I have generated a dxf file but when I opened it with AutoCAD, crashes AutoCAD and gives a message ID 11 incorrect: already used.
the dxf content: https://github.com/tarikjabiri/dxf/blob/dev/examples/latest.dxf
I can't spot the problem 3 days I am trying to solve it.
I think something wrong with the APPID because it holding the ID 11 or the Handle in the language of DXF.
I have a dxf working: https://github.com/tarikjabiri/dxf/blob/dev/examples/Minimal_DXF_AC1021.dxf
Thanks in advance.
There are two minor issues:

I´m having an issue with a DXF code for an Ellipse, I´m trying to have it Graphed by AutoCad 2019 but it won´t recognize the code for an unknown reason. I would greatly apreciate any insight on the issue. Thanks a lot in advance

Well, you are missing some AutoCAD 'housekeeping' stuff in your dxf file. You have all the geometry bits for your ellipse, but AutoCAD doesn't know where to put them in the overall DXF file. So you have to include things like the drawing 'Handle' and the other required elements that place the ellipse in the overall framework of the whole drawing. An ellipse in a DXF file starts out like what is shown below:
ENTITIES
0
ELLIPSE
5
86
330
70
100
AcDbEntity
8
0
100
AcDbEllipse
10
43.6886
20
16.2019
30
0
The R2000 dxf spec will tell you what all those pieces are for specifically, but everything above
AcDbEllipse
10
is needed to place the ellipse in the greater context of the rest of the drawing. Without it, the ellipse would not be recognized.
I can tell you that code 8 identifies the layer the entity is on, in this case, 0 and code 5 identifies a unique handle (id code) for the entity, in this case 86. The handle must be unique for every entity in a dxf file. If you are manipulating/creating dxf entities in code, you have to be very careful to never have duplicate handles.
This ia an example of DXF with a line from 100,100,0 to 200,200,0

I think that I'm exceeding EPS max line limits:
I'm generating an eps programmatically that consists of a grid of pictures.

So the thing is if I write up to 4 images to the EPS, everything works fine, but when I try to write a 5th, the eps won't open on any EPS viewer including Adobe Illustrator (the operation cannot complete because of an unknown error).
I tried using different images to make sure that the particular images were ok and I got the same result, as long as I'm writing 4 images (105825 lines file) everything works. But when I use 5 (132253 lines file) it fails.
Is it possible that I'm exceeding the maximum line limit for EPS?
This are the files in question if you'd like to analyze them:
the one that works - >https://files.fm/u/bfn2d32m and the one that doesn't ->

There's no 'line limit' in PostScript or EPS, so you can't be hitting that.
When I run your file through Ghostscript it throws an error /undefined in yImage (I'd suggest you debug PostScript using a proper PostScript interpreter, not Adobe Illustrator).
This suggests to me that one of your images is using more data than you have supplied, so the interpreter runs off the end of the data, consuming parts of the program, until it has read sufficient bytes from currentfile to satisfy the request. At that point is starts processing the file as PostScript again, but the file pointer now points to the 'yImage' of the next 'DisplayImage'. Since you haven't defined a 'yImage' key, naturally this gives you an 'undefined' error.
From your description, this would seem likely to be the 4th image, since adding the 5th throws the error. Note that if your program terminates without supplying enough data (so the interpreter reaches EOF) then the data supplied will be drawn. So it might look like your 4th image is correct even when it isn't, provided it isn't followed by any further program code.
A style note; PostScript is a stack-based language, so normally one would proceed by pushing values onto the stack and reading them from there, instead of executing the 'token' operator.
So your input would be more like :
0 0
564 608
12
564 608
0
0
DisplayImage
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
...
And the DisplayImage code would be :
/DisplayImage
{
%
% Display a DirectClass or PseudoClass image.
%
% Parameters:
% x & y translation.
% x & y scale.
% label pointsize.
% image label.
% image columns & rows.
% class: 0-DirectClass or 1-PseudoClass.
% compression: 0-none or 1-RunlengthEncoded.
% hex color packets.
%
gsave
/buffer 512 string def
/byte 1 string def
/color_packet 3 string def
/pixels 768 string def
/compression exch def
/class exch def
/rows exch def
/columns exch def
/pointsize exch def
scale
translate
This avoids you having to use token at all for the scale and translate operations for instance.
I use F95/90 and IBM compiler. I am trying to extract the numerical values from block and write in a file. I am facing a strange error in the output which I cannot understand. Every time I execute the program it skips the loop between 'Beta' and 'END'. I am trying to read and store the values.
The number of lines inside the Alpha- and Beta loops are not fixed. So a simple 'do loop' is of no use to me. I tried the 'do while' loop and also 'if-else' but it still skips the 'Beta' part.

The simple short code is :
program test_read
implicit none

double precision::r,t,rr
character::dummy*300
character*15::du1,du2,du3

100 read(10,'(a100)')dummy
if (dummy(1:3)=='END') goto 200
if(dummy(2:14)=='Alpha Singles') then
i=0
160 read(10,'(a4,i2,a6,i1,a4,i2,a6,i1,f12.6)')du1,b,du2,c,du3,d,du4,e,r
do while(du1.ne.' Bet')
write(*,'(a2,a4,i2,a6,i1,a4,i2,a6,i1,f12.6)')'AS',du1,b,du2,c,du3,d,du4,e,r
goto 160
end do
elseif (dummy(2:14)=='Beta Singles') then
170 read(10,'(a4,i2,a6,i1,a4,i2,a6,i1,f12.6)')du1,b,du2,c,du3,d,du4,e,r
if((du1=='END'))then
stop
else
write(*,'(a2,a4,i2,a6,i1,a4,i2,a6,i1,f12.6)')'BS',du1,b,du2,c,du3,d,du4,e,r
goto 170
end if
end if
goto 100
200 print*,'This is the end'
end program test_read
Your program never gets out of the loop which checks for Beta because when your while loop exits, it has already read the line with Beta. It then goes to 100 which reads the next line after Beta, so you never actually see Beta Singles. Try the following
character(len=2):: tag
read(10,'(a100)')dummy
do while (dummy(1:3).ne.'END')
if (dummy(2:14)=='Alpha Singles') then
tag = 'AS'
else if (dummy(2:14)=='Beta Singles') then
tag = 'BS'
else
read(dummy,'(a4,i2,a6,i1,a4,i2,a6,i1,f12.6)')du1,b,du2,c,du3,d,du4,e,r
write(*,'(a2,a4,i2,a6,i1,a4,i2,a6,i1,f12.6)')tag,du1,b,du2,c,du3,d,du4,e,r
end if
read(10, '(a100)') dummy
end do
print*,'This is the end'
