I don't know if this is true across platforms and versions of Stata, but it
is the case that if you're working in windows with a 32 bit version of Stata
10 there's a trade-off between the maxvar setting and the mem setting. If
you don't really have 30,000 variables try lowering maxvar and you may be
able to allocate more memory. If you actually have 30,000 variables, you
might want to start by narrowing that down before trying to merge.

Subject: st: memory problem
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
--------------------------------------------------------------------
Details of set memory usage
overhead (pointers) 2,144 0.00%
data 10,380,712 0.97%
----------------------------
data + overhead 10,382,856 0.97%
free 1,063,358,960 99.03%
----------------------------
Total allocated 1,073,741,816 100.00%
--------------------------------------------------------------------
Other memory usage
set maxvar usage 12,001,730
set matsize usage 1,315,200
programs, saved results, etc. 5,649,298
---------------
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!
