-h limits- (in Stata 10) does indicate that IC can handle 2,047 variables,
though. What happens when you run this example code?


vers 10.1

set obs 1000

forv i=1/165{
	gen var`i'=irecode(runiform(), 0, .2, .9, 1)

contract var*

su _freq, d

Betreff: st: problem with -contract-

I was wondering if anyone could help with a problem i am having using
-contract-.  I wish to use contract on about 165 variables at the same time,
this would create a dataset containing 166 variables if contract worked.
however Stata (of which I am using version 10, IC)  cannot do this due to
too many variables.  Is there another way to create the frequencies I
require or to alter -contract- in some way to allow this many variables?

Thank you,
