Hi Guys,

I am using a pointer as shown below

        Locat_Pointer= ^ Locate
        Locate= Record
                 next:locat_pointer;
                  Code:word;

How to assign USer input to pointer variable run time in free pascal Like Below

       Locate_Pointer^.code:=.....?

thanks
Sud

Yes, that's about right, use something like

         Locate_Pointer^.code:= w;

where w is a word read in using something like the example code Marco pointed you at a couple of days ago (if there's something you don't understand in that I suggest raising it in that thread, rather than starting another one).

Remember that you'll need to allocate each record with the next pointer set to nil, and will also need to deallocate each one precisely once when it's no longer needed. In practice most people would use a more recent structure such as a TList, TStringList etc., what you've got there is rather 1970s code and since then there's been consensus that programs don't have to be written by reimplementing Lisp.

Hi Sud,

If you ask about conversion of the input read using ReadLn into a string variable to the word variable, then one option would be using procedure System.Val (see http://www.freepascal.org/docs.var -> "Run-Time Library (RTL) units reference manual" -> "System" -> "StringFunctions" -> "Val").
