begin;
write('Enter a string: '); readln(s);
for i:=1 to length(s) do
ascii[i]:=ord(s[i]);
{ s[i] accesses each element of the string as a char.
ord returns the ASCII value of the char. }
writeln('ASCII vals: ');
for i:=1 to length(s) do
write('|',ascii[i],'|');
{ Generate a random key }
code:=Random(1000);
writeln;
writeln('the random key is : ',code);
writeln('the encrypted message is :',sum(ascii)*code);
end.
```

After showing this to him, he said i should use Lazarus to create the application with GUI and use A menu that can allow me choose to input a string and then encrypt it. I have tried it on Lazarus but failed and i dint understand the menu. please i need help, Its a assignment.

one of the thing i don't understand is why the 'random2' procedure doesn't seem to work in the general program, even though it works well when i call it from the procedure 'cargarMatriz'.. and also when i execute it the program it work fine for a while, but after a certain point just it stops displaying.. before ending the game..

Well, i'm a fresher so any hints on a more appropriate aproach will be helpfull..

result := vpmPasTcpClose(conn);

mutex := 0;

end;

end;

As you can see. some measures have been done against calling PC/TCP close reentrantly. If I comment out the PC/TCP call, everything works OK, so it seems to me that the problem is in calling PC/TCP. I failed to fix this:

1) It does not matter whether I intercept int $08 or int $1c - everything is the same.

2) Locking code segments using {$C FIXED PERMANENT} directive does not help.

3) Switching to a specially allocated new stack after calling the previous handler (and restoring the original stack pointer after PC/TCP call) does not help.

4) Using "call real mode procedure with an IRET frame" DPMI function instead of "simulate real mode interrupt" does not help.

5) Providing a real mode stack for the PC/TCP call (by allocating a real mode memory block and placing its address in the DPMI real mode registers structure) does not help.

In any case DOS hangs.

As I noted above, in real mode everything is OK (of course, in real mode I am using int $61 directly instead of DPMI). Calling the same close connection function in protected mode from the main code (not from the interrupt handler) does work.

What may I be doing wrong? Is there anything else that I don't take into account? Is it anything in PC/TCP that prevents calling it from an interrupt handler? If so, what to do?

]]>Make a program in Pascal that after has read a text with a list of nums., it will return the numb. of the nums that appear less than one times in the text.

The text that will be read from the program should be like that.

In the first line there are two nums. seperated by a space, n and m. N is the number of nums that exist, like if the text contains the numbers 1,2,3,4, n is 4 (1..n).

M is how many lines follow.

Every line has a couple of nums, a,b, (1=<a=<n), (1=<b=<n) (a<>b)

a and b are separated by a space.

The file that the program will make will have written on it a num., that says how many nyms are appeared less than two tims in the text.

All the nums. are Integer.

0=<p=<n

i've made the following program, but it only reads the first line of the text. Anyone that can help me? The deadline is almost ended. Thanks in advance.

I've made the code after that, the program is how to put into variables all the nums.

The file represents stock as it is purchased. Therefore more products may be added to it of different/same sizes and barcodes. Each individual item creates a new record whether it be a new size or barcode for example if you have two products of the same barcode and size it stores them as two records. I need a procedure which sorts the records into ascending order of the barcodes and combines the sizes to one record and marks the others for deletion so that the file is like the one in the image below:

-1 means its marked for deletion

I am storing all block data in an array of records, each with a "noiseID" entry, which is the data generated by the "PerlinNoise" function, and decides what the block should be.

The PerlinNoise function, however, is not working. I followed the instructions on this site and transferred the code over to pascal:

http://freespace.virgin.net/hugo.elias/models/m_perlin.htm

However, the "smoothNoise" function is not working properly. Once called, the program exits with code 217. The output says "range check error", but I don't see how anything is out of range.
