Hi Steve,

  Thank you very much, was able to resolve the issue after adding 
the writeln within the braces, I am trying to implement a data 
dictionary compressing using D, and had 2 issue and this is one 
of the issue, and the other issue is detailed in the post "Error: 
variable i cannot be read at compile time", which contains the 
details of this program, if possible can you please help on on 
the other issue in the post "Error: variable i cannot be read at 
compile time".

From,
