Elements of a vector are implicitly enclosed, so remove the enclose: +2⎕NQ'CPro.Class.Root.Control.FM85.TM2' 'LockRows' ⍬ It is only required if the zilde would be the one and only parameter. In that case it needs to be converted into a scalar or one-element-vector by enclose or comma enclose, as it ...
