*DATE on DSPF program

Mark,

Perhaps a minor point, but CAxx actually indicates that no input data
is transmitted from the device.  WSDM, which in this case is what/who
is working with the device, does return data to the application program.
That is, the RPG program is expecting a buffer to be returned to it
following the READ/EXFMT operation.  WSDM will not return what is current
on the device in the case of CAxx; but rather what the last view of the
data was.
