Subject: RE: counter variable
Dear Peter:
Could I ask you another question?
I tried to write a sas code to produce new variables (D2001-D2006,
actually
I ignore months in this example!) relating to old variables (P_01-P_99)
as
below and have some problems in doing so.
(1)Why can't I use "D&y" in the following sas code
(2)Should I write "output;"?
data test; set a;
array P(1:99) P_01-P_99;
do yyyy=2001 to 2006;
call symput('y',trim(left(yyyy)));
i= (yyyy - L1_yyyy)*12;
if i>=1 and i<=99 then
D&y= P(i);
output;
end;
run;
Thank You in advance for the kindly reply!
Simon
