Hello.
 Im running into a problem I cant seem to explain. for some reason,
when I put a variable (integer) as an argument in a for loop. It 
crashes my system. I am still using turbo pascal 5.0
example:

 procedure makescreen;
   var level :integer;
       i     : integer;
  begin
    level := 1;
    level := level + 4;
    for i := 1 to level do  {this is the line that wonks my program..}
     begin
      { code.. code.. code..}
     end;
  end;

and if I call this procedure.. WHAMMO! I am creating a video game and
when it comes to this procedure, all these random pixels fills up my
screen and locks up my system.. I have to cold start my system to get it
back running.. but if I put a integer.. ie.. 4 or sumthin in the for i
statement.. everything is hunky dory.. am I missing something here? any
comments help.. is appreciated.
								thanks.
