Forums Scripts & Popups text buffer size in dialog

it's something like,,,

edit "end of file list", id, x y 500 400, multi, hsbar, vsbar, tab num

(edit box in a dialog)

and access using did -i to insert text (filename) at line 1

$maxlenl , 8192,,, I'm getting about 400 lines at say 60 chars each before the edit box doesn't update with the next filename, so my edit box is getting about 24,000 chars.....approx
