*Stata programming by Example
*Tutorial 1


* writing Stata programs can be done in the Stata do editor
* to open the do editor type the following on the Stata command line

doedit   //opens do editor

*or use the "New Do-File Editor" Icon


**Example 1, this runs a few Stata commands

*--------------Start Example  1 ----------------*

sysuse auto, clear   //loads auto dataset  after clearing existing data from computer memory
describe
summarize

*--------------End Example----------------------*






*Example 2 - This starts a do file from the Stata commandline
*You need to do the following to get this to run:
***copy Example2 (below) to a new page on the do editor, by doing:
*****highlight example 2
*****right click to copy
*****press blank page icon on the do editor
*****right click to paste

*Then save file  eg. press floppy disc icon and give it a location and name (save as a .do extension)


*Then to run Example 2 as a saved do file:
*****type on the Stata commandline "do" and the file name (file path if necessary)
*****eg. assuming that the just saved do file is in c:/data , this is what you would type: do c:/data/example2


*--------------Start Example  2 ----------------*

sysuse auto, clear   //loads auto dataset  after clearing existing data from computer memory
describe
summarize 

*--------------End Example----------------------*





*After having first done example 2 then you can do example 3. This runs a do file from the Stata do editor

*--------------Start Example  3 ----------------*

do c:/data/example2  //the do file path and name must correspond with that given in example 2


*--------------End Example----------------------*
*see help do






*Save example 4 the same way as you did for example 2. But to run this also type a variable 
*name 
*eg.   do c:/data/example4 mpg


*--------------Start Example  4 ----------------*

sysuse auto, clear   //loads auto dataset  after clearing existing data from computer memory
describe
summarize `1'

*--------------End Example----------------------*
*see Stata 10 Users Guide 16.6.1





*Save example 5 the same way as you did for example 2. But to run this type also type a variable 
*name  
*eg. do c:/data/example5 mpg price


*--------------Start Example  5 ----------------*

sysuse auto, clear   //loads auto dataset  after clearing existing data from computer memory
describe `1'
summarize `1' `2'

*--------------End Example----------------------*
