----------------------------------------------------------------------

SUPPOSE THAT I WANT TO GENERATE
100 NUMBERS FROM A POISSON WITH PARAMETER LAMBDA=25.
I USE THE SYNTAX:

. clear
. rndpoi 100 25

AND I GET THE MESSAGE:

rndpoi: ado-file does not define command
r(162);

----------------------------------------------------------------------

I USE THE SYNTAX:

. search rc 162

AND GET THE MESSAGE:

[P]     
error  . . . . . . . . . . . . . Return code 162
ado-file does not define command;
The first program in any ado-file must be named the same as
the ado-file name.  For example, xyz.ado must begin with
program define xyz.  The command you typed has loaded an
ado-file that violates this rule.

----------------------------------------------------------------------

I COPY AND PASTE THE BEGINNING OF THE FILE rndpoi.ado
AND GET:

*!version 1.1 1993 Joseph Hilbe, Walter Linde-Zwirble   (sg44: STB-28)
* revised 10Mar97 Hilbe with assistance from Guy van Mille  STB-41 sg44.1
* Poisson distribution random number generator
* Example: rndpoi 1000 4  [set obs 1000;  4 is the mean]

program define rndpoi1
   version 3.1

IT SEEMS THAT THE FILE rndpoi.ado CONTAINS A
PROGRAM (ADO FILE) CALLED rndpoi1.ado (SHOULD BE rndpoi.ado ?).
 
----------------------------------------------------------------------

I WANT TO CHECK IF MY PACKAGE IS UP-TO-DATE,
SO I USE THE SYNTAX:

net install sg44_1.pkg

AND I GET THE MESSAGE:

package installation

package name:  sg44_1.pkg
        from:  http://www.stata.com/stb/stb41/

checking sg44_1 consistency and verifying not already installed...
all files already exist and are up-to-date.

----------------------------------------------------------------------

THIS PROGRAM WAS CREATED IN 1993.
PROBLEMS, IF ANY, WERE REPORTED AND CORRECTED.
FOR EXAMPLE, rndbin WORKS FINE.
SO, I DO NOT UNDERSTAND WHAT IS HAPENING TODAY.
