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
