     i need the CSV import "/ENCODING" option which has only been added in
     June 2012.
     Lets imagine I would find/build a recent version of the PSPP-Perl module...
     Do you think it would perform significantly better in regards to memory
     and speed?
     Right now I am dynamically generating the PSPP-Skripts and that works
     perfectly - except for huge memory demand vs. slow performance tradeof.
     Do you know any good reason - or does you stomache tell you somehow -
     that it would need less memory?
Using the perl module will be  magnitudes faster and use less memory than
than using PSPP, the program.    This is because all it does is copy data,
whereas PSPP is a very sophisticate statistical analysis program and 
has to do lots more work.

Your mention of the /ENCODING option, however confuses me, because it is not
something that is relevant to the perl module.
