You can use %Library.ScrollableResultSet or Execute the query again.

If you have an array you can:

set txt(1)="1
...
set txt(n)="n


ClassMethod write(txt As %ArrayOfDataTypes)
{
  set​ arg1=$get(txt(1))
  ...
  set arg2=$get(txt(n)

or

  set l="" for i=1:1 {
         set l=$order(txt(l))
         quit:l=""
         set arg(i)=txt(l)​​​​​​


}

and call it with the array ByRef:

do ..write(.txt)

Hey Duncan,

you also can use $CLASSMETHOD or $METHOD.
