Hi,
please help me do this
all dates are in date9. format
do I need an array???
/*HAVE*/
admit_dt Pdate1 date2 Pdate3 Pdate4 Pdate5
01OCT13 02oct13 09oct13 11oct13 15oct13 01OCT13
/*logic*/
Pdate1-admit_dt=PRday1
Pdate2-admit_dt=PRday2
Pdate3-admit_dt=PRday3
Pdate4-admit_dt=PRday4
Pdate5-admit_dt=PRday5
/*WANT*/
admit_dt Pdate1 Pdate2 Pdate3 Pdate4 Pdate5 PRday1 PRday2 PRday3 PRday4 PRday5
01OCT13 02oct13 09oct13 11oct13 15oct13 01OCT13 1 8 10 14 0
Thanks
The only possible mistake I see is that you have Admit_date1 rather than Admit_date in your example above.
Other than that it should work, if it doesn't you'll have to post the error or why it isn't.

You don't need an array but it helps avoid the repetition of code.
What have you tried?
You can flip the above for starters:
PRDay1=Pdate1-admit_dt to get what you need without going into arrays.
thanks for the reply.
I wanted to write the way you mentioned.
But there are 65 Pdate's
so I was trying to see if there is any easier way???
Thanks
You've asked at least a dozen questions on arrays here. While I don't mind helping, you should try to do some of it on your own otherwise you'll always be dependent on the forum.
hmmm
it has always been a learning process for me.
this is what I tried
please correct me
thanks
data array;
set demog;
array prox{*} PROCDT1-PROCDT65;
array pr{*} PRDAY1-PRDAY65;
do i=1 to dim(prox);
pr{i}=prox{i}-ADMIT_DATE1;
end;
run;

thanks you so very much.
I get some results.
Thanks
