Ken, I already answered your a) & c) questions on another board and provided code for you to use.
If you are wanting to get the list from a .tls or .txt file then use the fopen( filename, mode ) command to open whatever file you want to get the list from ... the fgets( filehandle ) command to read line items from the file ... the CategoryAddSymbol( symbol, category, number ) To add the symbol(s) to whatever category and the fclose( filehandle ) To close the file when you are done. Books, Documentation & Help Files are wonderful things especially when one actually uses them. --- In [email protected], Ken Close <[EMAIL PROTECTED]> wrote: > > Joe: thanks for this detail.
