About FileRead()

Posted on 1998-04-15

Can I, using FileRead(), read integers from a file and not bytes?
For example if my file is like this:

12 32

How can I read only the two numbers and not the space between them?

Thanks for your help

Sorry, NO(with fileread)
The easiest way is to open file and read it as a traditional pascal as  
  ReadLn(f,integer1,integer2) which reads the above line.
Of course you can do it with FileRead but not automatically, you should parse the line by yourself.

As mentioned above, it's not possible to access data as integers directly. But you could read data like


If (Byte3 AND 127)>0 then
  i:= -(Byte3*$1000000+Byte2*$10000+byte1*$100+Byte0);
End else
  i:= Byte3*$1000000+Byte2*$10000+byte1*$100+Byte0;

But this is not a rather cool way to solve it. The FileRead operation is a lowlevel routine. Avoid using it if possible.
