=====Getting the current line number=====

//by Jon Ripley, Richard Russell, January 2012//\\ \\  The **FN_linenumber(!384)** function returns the line number of the currently executing line of code as demonstrated below.\\ 
<code bb4w>
  12345 PRINT FN_linenumber(!384)
        END

        DEF FN_linenumber(E%)
        LOCAL p%% : p%% = PAGE
        WHILE ?p%% AND p%% + ?p%% < (E% + PAGE - !340) p%% += ?p%% : ENDWHILE
        = (p%%?2*256+p%%?1)

Always pass **!384** as the parameter to FN_linenumber, this [[/Interpreter%20internal%20variables|interpreter internal variable]] is the pointer to (or within) currently-executing statement.
