It is because the text/file parameter of assign()  is a "var"  
parameter, and "var" means that the input should already be valid.  
For some reason, all the assign() variants are defined as

Procedure Assign({$ifdef PARAOUTFILE}out{$else}var{$endif}  
t:Text;const s:String);

I don't know why this "PARAOUTFILE" is never defined (maybe a bug in  
the compiler which causes problems when defining a text/file  
parameter as "out"?)
