Evaluate and unit reference

Hi, 

I have general purpose CSV FIle compare function in one  unit (lets call it general)

I'd like to call it from actual test unit.  (lets call it actualtest)

Problem is that I need to ignore / modify some fields before compare.

I tought that i could pass procedure name as parameter and call it from that compere function, but I get Unknown identifier  actualtest

 

for example

in general.sd

 

procedure compare_csvfile (file1, file2, comparemethodname);
begin
  ...  
  parameters := '( something )';
  evaluate(comparemethodname+parameters);
end;

in actualtest.sd

 

uses general;
procedure normalizedata(a,b,c);
begin
// do something
end;

procedure doactualtest;
begin
  ... generate test data ..
  compare_csvfile( file1, file2, 'actualtest.normalizedata');
end;

should this be possible?
