Desire:
Routine A is invoked with >1 attached documents. This routine
then _Launches Routine B which can examine the same documents.

Reality:
Routine A is invoked and GetAppParms shows
the attached documents with valid names and valid working
directory numbers. However, when Routine B starts up
ONLY the first document has a valid WDRefNum.

Notes:
Working directories associated with Routine A are closed
following the completion of this routine (standard MF
procedure). Thus the working directories corresponding to
documents 1 to N are closed. Somehow (!) the first document
receives a NEW working directory (i.e. a new WDRefNum is
allocated). The remaining documents do not - their invalid
WDRefNums are retained.

Question:
ANY working directories I open up in Routine A get
closed and  disk directory numbers are generally not
suitable, so how does one pass more than one document to
a Launched routine?
