Right. And back Wed, 9 Jul 2008 (10:55:10 -0700) you asked, "Is there
any way to lag a string variable?", i.e. your ID.
And yes, Lag works fine with string variables. I think both Gene and
ViAnn Beadle have told you that.
The problem is that variable 'lagged' is *NOT* a string variable; so,
you get the "Invalid combination of data types." A new variable is a
string variable only if it's declared on a "STRING" statement.
I don't see your stating how long 'ID' is. If it's 11 characters,
this will work:
compute lagged = LAG(ID).
And none of this has anything to do with file size.
