Make sense. It would be quicker to write a loop to scan the string counting lineendings rather than using all those pos calls. Eliminates the overhead of having to make those calls. Since there doesn't appear to be any known built in solution for this I think I'll do just that. THX - Jon -- Jon Foster JF Possibilities, Inc.

Re: [Lazarus] How to find position in TMemo.lines
I'm using the default GTK widgets.It would seem to me that the widget has to already be aware of this information. Is there some way to get it to give it up? I'm ignorant of the interactions between GTK and Pascal or even how GTK functions. It would take me considerable time to trace through the code to figure this out. If no one else knows a method to do this I think I'll go with Henry's idea. THX - Jon Felipe Monteiro de Carvalho wrote: You can submit a bug report asking for CaretPos to be implemented.
