alternative to call parameter?

[pcoder 5]

procedure TObj.run;
var r: TRecord;
begin
...; processRecord( r); ...;
end;

ProcessRecord is a method and contains many nested calls (more methods).
The issue is that many methods would need an additional parameter (very cumbersome).
Therefore an alternative is wanted. Object-field FR (PRecord) is a pointer (rather than record) to reduce memory outside of runs.

is there any preference for one of them?

procedure TObj.run2;
begin
  new( FR); 
  ...; processRecord; ...;
  dispose(FR);
  FR := nil;
end;

procedure TObj.run3;
var r: TRecord;
begin
  FR := @r; 
  ...; processRecord; ...; 
  FR := nil;
end;

I would choose the latter. No need to allocate memory dynamically unless the record instance needs to live after TObj.run3() exits. 

 

But, if you have a lot of methods of TObj that are acting on the record then they should instead be methods of TRecord itself. Consider refactoring your code to make it cleaner.
