st: gra command

[Guelmbaye Ngarsandjé <guelmbaye@hotmail.com>]

Dear stata users, 
 
 I have been looking to check the strutural break in my data and found  
 that cusum6 helps do it. However, the file I found has some commands  
 that don’t work when I type them. For example using greenedat.dta from  
 P.136 provided by the file is the command: 
 
 “gra gpop petindex, s([year]) xlab ylab” which gives the following  
 message : “Unrecognized command: gra” 
 
 The support file can be found at:  
 http://personal.rhul.ac.uk/uhte/006/ec5040/Cusum%20test.pdf 
 
 What am I doing wrong? In the mean time I want my X axis to be fully  
 labelled by the periods but when trying to edit the cusum graphs I  
 receive “This is not a “live” graph and therefore cannot be edited.”  
 How to obtain my periods labelled at 45 degrees on the X axis? 
 
 
 Thanks for the help.
