st: memory problem

["Elizabeth Sheila Germana" <egermana@ioe.ac.uk>]

Hi, 
 
I'm encountering problems when I try to merge a file. 
 
My memory details and syntax are the following:
 
memory

set maxvar 30000
set mem 1g
set more off
                                                  bytes
--------------------------------------------------------------------

                                        ---------------
    Total                                    18,966,228
-------------------------------------------------------
Grand total                               1,092,708,044


I think that I have enough memory however, I have tried to extend  memory more than 1g but I can't. 
What could be the problem?
 
Thanks for you help!
