[texhax] some problems about \prevgraf and \toks

[Chakrit Nimmanant]

Dear Sir,
             I have 2 questions about my macro, Can you please recommend me 
some instructions?

So, my question is how can I refer to the current line number or at least 
how can I know that whether TeX has already entered a new line or not?

>Secondly, I have my macro like this:
      \def\marginparR#1{%
             \justReceivedToks = {#1} % this will keep currently  received 
argument in a \toks.
             \tempToks = \allEarlierArgumentConcatTogether % this will back 
up value with temp \toks
             \allEarlierArgumentConcatTogether = " 
\allEarlierArgumentConcatTogether " concatenate with "\justReceivedToks"  % 
this line is my problem because I can't concatenate 2 tokens and assign it 
to another token like A = A.concat(B); in Java Programming.
So, my question is how can I concatenate two "\toks" and assign it to 
another "\toks"?

                                                    Many thanks in advance 
for any assistance you may provide.
                                                                             
           Chakrit.
