Thanks for the answer. I tried that and the results is "package not found".

Try -ssc uninstall tabulate- and -ssc uninstall tabulate- to check if
the update matters only for the -tabulate- in use.

Any other opinions?

The only suggestion so far is that I update my Stata. But I am fully updated
and there are no further updates available, so that is not the problem.

I am very concerned because there are no errors or any other problems
whatsoever that would indicate a faulty installation or the like. There are
no red flags, only clearly incorrect output.

Hello Stata-listers,

I am running into the following very odd problem: I have a factor variable
that I would like to -tabulate-, but every time I use -tab-, I get different
results. When running -tab- back to back on the same variable in the same
data set I get entirely different results every time.

All the years that I have used Stata, I've never had anything like this
happen, so I am totally stumped. There are only 2 variables in my data set:
a variable "ID" that is storage type double and the variable "pldel" that is
storage type byte.

Please see what I copied and pasted at the end of this email straight from
my interactive session. The same oddity occurs if I use the -tab pldel,
gen()- syntax; in that same session I continue to get different results
every time I run a simple tab, so the below are just two arbitrary examples.

If I open a new clean session of Stata, then tab works as expected. I did
not define any user defined programs or do anything anything else of that
nature in the broken session. The only commands in my Command History are
various versions of -use-, -tab-, -count-, -describe-, and -browse-.

So, what might have happened to break a basic command like -tab-? I know
that using a new session fixes the immediate problem at hand, but I want to
ensure that something like this does not happen in any of my data analyses
in the future!

If it matters, I'm running Stata 12.0 SE 64-bit on a Windows 7 machine.

I apologize if this has been discussed before, but a quick preliminary
search turned up nothing. I would appreciate any help troubleshooting.
