Re: [amibroker] Question on VarSet and VarGet for Tomasz and programming gurus

["Tomasz Janeczko" <amibroker@xxxxxx>]

Gary,
 
One example (trivial) application:
 
instead of writing:
 
C1 = Ref( C, -1 );<FONT face=Arial 
size=2>
C2 = Ref( C, -2 );

C3 = Ref( C, -3 );

C4 = Ref( C, -4 );

C5 = Ref( C, -5 );

C6 = Ref( C, -6 );

C7 = Ref( C, -7 );

C8 = Ref( C, -8 
);
C9 = Ref( C, -9 );
 
You can now write single line that will have the 
same effect
 
for( i = 1; i < 10; i++ ) VarSet( "C"+i, Ref( C, 
-i ) );
 
Best regards,Tomasz Janeczkoamibroker.com

  and VarGet for Tomasz and programming gurus
  
  Tomasz,
   
  For us non-programmers, I get the sense of importance that VarSet 
  and VarGet offer, but not in the practical sense.
   
  For PT, is there a way to find out which positions are open, what there 
  positionscores are, etc. using these functions.
   
  I'm sure you have some very practical reasons for offering such 
  functionality, but I'm not seeing it.
   
  Thanks,
  Gary
