close a file (.sav) with syntax)

[drfg2008]

I simply want to close a .sav File with syntax.

(The reason is a littly tricky: Thanks Jon Peck, but there is one problem left. If you just select cases -not permanent- and save the file with the selected cases, unfortunately all cases are saved and not only the selected. Maybe there is a possibility to save only selected files. As far as my capabilities in SPSS-Syntax are concerned you have to use "SELECT IF group =1." But that's permanent. So I need a syntax to close the 'old' file and open the original again.)

Thank you

If you have only one active dataset, just open the file--the file on disk will replace the one you're working with.

If you have multiple datasets on the go, use DATASET CLOSE.  See examples in the Help.

If what you want is to save subsets of cases without discarding them from the active dataset, do this.

temporary.
select if ...
save outfile=...

If you want to partition your dataset according to the values of one or more splitting variables, you might consider the SPSSINC SPLIT DATASET extension command.

Thanks, temporary worked!
Thanks also to "SPSSINC SPLIT DATASET extension command" I'm checking this right now.


This is a working Syntax (with my more elementary version). But it's quite fast.
