Erasing Portable subfile

[Guy Werry]

Yes, Richard, it can be done.  I know that I've done this routinely with
regular subfiles. (Ux 10.2, Ph 7.33.D3).

Often I will use qtp to create a one record subfile, so that I can then use
the subfile in a Quick screen.  I will do the following:

* Create using Qtp (personal preference, Quiz can also be used)
* I now have either:
  * FRED.sf
  * FRED.sfd (for regular subfiles)
 OR
  * FRED.dat
  * FRED.idx
  * FRED.sfd
* I just do 'rm FRED.sf' or 'rm FRED.dat' 'rm FRED.idx'
* Then I do a 'touch' on the file(s) that I've just removed.  

So, that should work with portables as well.

Does anyone know if it is possible to erase the data portion of a portable
subfile (on Unix) while maintaining the dictionary structure? Typically
these subfiles exist as 3 files something.dat, something.sd and
something.idx. Can I simply remove the dat file and recreate with touch? Or
do i have to recreate? Thanks.
