Subject: Empty string as SNL macro

Hi,

I would like to send an empty string as the value for an EPICS SNL program. But when I do it like this


seq testSequencer, "D=TOF,P="


the result is that the SNL code does not recognize that I override the default value of macro P
(which is not an empty string). Is there a way to pass an empty string as the macro value to the
sequencer program directly from the "seq" command without manipulating non-empty strings
in the code itself?

Thanks,
  Hovanes Egiyan.
