know if a variable is defined

Victor Casajuana Mas

Hi everyone.

How can I tell if a variable is defined in PascalScript?

Thanks!

gpi

uses fs_iinterpreter;

var i: integer;

   v: TfsCustomVariable;

begin

    for i:=0 to frxReport1.Variables.Count-1 do

      if frxReport1.Variables.Items[i].Name[1]<>' ' then

        ShowMessage(frxReport1.Variables.Items[i].Name);

    for i := 0 to frxReport1.Script.Count - 1 do

      begin

        v := frxReport1.Script.Items[i];

        if v is TfsMethodHelper then

          ShowMessage(v.Name+' '+TfsMethodHelper(v).Syntax+' '+TfsMethodHelper(v).Description);

      end;

end;
