I understand in Stata, command D. means the first difference,
what is command l. means? is it the lag difference? can someone 
please tell me the meaning of command l.?

D. and L. are not commands but operators.
 
Important information on time series analysis is documented in 
difficult-to-predict places. Try:
 
   . search time series varlists
 
   [U]     Chapter 11  . . . . . . . . . . . . . . . . . . . . .  Language syntax
           (help language, prefix, varlist, exp, if, in, weights,
                 using, options, numlist, datelist, tsvarlist)
 
You get the information you seek by:
 
   . help tsvarlist
 
Hope this helps
Svend
