CSV Generation Loading Entire SAV

[Dave Trollope]

Hi,

We are using the following script to generate CSV's for a subset of 
variables in an SAV file and it looks like pspp is loading the entire 
SAV file in to memory. (Some of our SAV files are quite large - 4GB). 
I'm wondering if there is an option or a way we can reduce the memory 
usage when extracting a subset of variables?

GET FILE = "{}"

SAVE TRANSLATE
  /OUTFILE="{}"
  /TYPE=CSV
  /FIELDNAMES
  /REPLACE
  /KEEP={}
  /MISSING=RECODE
  /CELLS=LABELS.

Cheers
Dave
