Works without a hitch on my Stata 10.0 under Vista. Next time, specify the
filename please. It takes ages to find from your description using things
like 

**********
fs *.dta
foreach file in `r(files)'{
di "`file'"
describe using `file',s
}
***********

And inspecting the resulting log for your vars...

Hello, i just started using STATA 10 in Vista

I was trying a couple of exercises from Christopher F. Baum's book: "An 
Introduction to Modern Econometrics Using Stata" by referring to his do 
files.

here is the dataset:

    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
        year |        77        1990    3.183014       1985       1995
      packpc |        77    87.16241    21.63518    49.2722   141.9558
      avgprs |        77    161.4092    36.29128   97.03333   239.1093
     stateid |        77    24.42857    16.77281          3         45
       incpc |        77    18.05913    3.505946   11.64714   25.80803

and its description:

  obs:            77
 vars:             5                          9 Jun 2006 14:07
 size:         2,156 (99.9% of memory free)
----------------------------------------------------------------------------
------------------------------------------------
              storage  display     value
variable name   type   format      label      variable label
----------------------------------------------------------------------------
----------------------------------------------
year            float  %9.0g
packpc          float  %9.0g                  packs per capita = packs/pop
avgprs          float  %9.0g                  average price during fiscal 
year, including sales taxes
stateid         long   %8.0g       stateid
incpc           float  %9.0g
----------------------------------------------------------------------------
----------------------------------------------

When i type in the command as he does in the do file once in a hundred time 
it worked, and gave me the following result, so i saved instantenously:

. reshape wide packpc avgprs incpc, i(stateid) j(year)

(note: j = 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995)

Data                               long   ->   wide
----------------------------------------------------------------------------
-
Number of obs.                       77   ->       7
Number of variables                   5   ->      23
j variable (11 values)             year   ->   (dropped)
xij variables:
                                 packpc   ->   packpc1985 packpc1986 ... 
packpc1995
                                 avgprs   ->   avgprs1985 avgprs1986 ... 
avgprs1995
                                  incpc   ->   incpc1985 incpc1986 ... 
incpc1995
----------------------------------------------------------------------------
-

But under normal circumstances;

. reshape wide packpc avgprs incpc, i(stateid) j(year)

(note: j = 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995)
variable stateid not found


this is the message i get.

I observed that normally, when i get the error message, the data name that i

am working is displayed next to STATA 10.00 such as: STATA 10.00 - C: 
blablablablab\cigconsumpw.dta

but at the one time it worked the display was such that: - STATA 10.00 - C: 
blablablablab\temp\blalal.tmp

Now, can anybody help me to make this work non-stochastically?

Thanks
