Hi Lin,

I tried like that already. Itried following giving missing values.

data test;

indt = '12Apr2011';

intm = '13:20';

dttm = compress(indt || intm);

sdttm = input(dttm, datetime. );

run;

Getting following error:

NOTE: Invalid argument to function INPUT at line 41 column 12.

indt=12Apr2011 intm=13:20 dttm=12Apr201113:20 sdttm=. _ERROR_=1 _N_=1

NOTE: Mathematical operations could not be performed at the following places. The results of the operations have been set to

missing values.

Each place is given by: (Number of times) at (Line):(Column).

1 at 41:12

Please help me ASAP because I need to find days and hours between start date time and end date time of symptoms.

Thank you,

Mikki
