wdselect=:3 : 0
0 wdselect y
:
if. 0=#y do.
  empty wd 'psel wdselect;pclose' return.
end.

'n s e'=. 3{.x

if. 2=L.y do. 'hdr sel'=. y
else. hdr=. '' [ sel=. y
end.

'r c'=. $,.>sel
sel=. ;sel ,each LF

'c r'=. (12,5*6>r) + >. 4 8 * >. c,r
c=. 205 <. 80 >. (4*#hdr) >. c
r=. 128 <. r

if. (<'wdselect') e. <;._2 wd 'qp' do.
  wd 'psel wdselect;pn '",hdr,'";'
else.
  wd 'pc wdselect;pn *',hdr
  wd 'xywh 4 4 ',":c,r
  wd 'cc l0 listbox ws_vscroll rightmove bottommove',s#' lbs_multiplesel'
  wd 'setfont l0 ',PROFONT
  wd 'cc e0 editm; setshow e0 0'
  wd 'xywh ',(":14+c),' 6 36 12;cc ok button leftmove rightmove bottommove;cn "OK";'
  wd 'xywh ',(":14+c),' 21 36 12;cc cancel button leftmove rightmove bottommove;cn "Cancel";'
  wd 'pas 4 2;pcenter;'
end.

wd 'set e0 *',sel
wd 'set l0 *',sel
wd@('setselect l0 *',":)^:(_1 -.@-: n)"0 n
wd 'setfocus l0'
wd 'pshow'

while. 1 do.
  wdq=. wd 'wait;q'
  ({."1 wdq)=. {:"1 wdq
  done=. (<'cancel') e. systype;syschild
  button=. systype -: 'button'
  ok=. button *. (<syschild) e. ;:'l0 ok enter'
  if. ok +. done do.
    wd (ok *: e)#'pclose'
    ok;".l0_select
