Multi Dimension Arrays

Happy Monday All!

So here is my questions that I hope can be solved with relative ease-

I have an array that works in that it calculates if notetime{i} is between the Unit_startTime_Day & Unit_EndTime_Day, tallies the sum of the entries that match and then keeps the notetimes that match the condition

But here is what I am trying to do-

In line2, I am trying to make it so that notetime4 becomes notetime1, notetime5 becomes notetime2, etc etc as there can be up to x number of notes but it becomes difficult for users to scroll through when its note22-note1000

code below table- I apologize in advance that there is no input table but hopefully someone can point me to the way...

Thanks in advance for your help.

data all_notes;
retain date time_days pt_hours total_notes;
merge unit_time note_times;
by PAT_ENC_CSN_ID;

array notes (*) note:;
array notep {&notect};
array notetime {&notect};
do i=1 to dim(notes);
if start2<=notes(i)<=end_t then notep(i)=1; else notep(i)=0;

if notep(i)=1 then notetime(i)=notes(i);else notetime(i)=.;
end;

total_notes=sum(of notep1-notep&notect);
format notetime1-notetime&notect datetime19.;
drop _name_ _label_ note1-note&notect /*notep1-notep&notect* i*/ department_id DEPARTMENT_NAME tot_hrs;
rename start2=Unit_StartTime_Day END_T=Unit_EndTime_Day time_days=pt_days;
if department_id=. then delete;

run;

pat_enc_csn_id	Unit_StartTime_Day	Unit_EndTime_Day	notetime1	notetime2	notetime3	notetime4	notetime5	notetime6	notetime7
1234	24Jul18:04:19:00	24Jul18:23:59:59	24Jul18:02:35:00	24Jul18:08:42:00	24Jul18:22:58:00	.	.	.	.
1234	25Jul18:00:00:00	25Jul18:23:59:59	.	.	.	25Jul18:03:25:00	25Jul18:08:18:00	.	.

Not too sure I understand but this might to do what you want:

data HAVE;
 infile cards dlm='09'x dsd;
 input PAT_ENC_CSN_ID	(UNIT_STARTTIME_DAY	UNIT_ENDTIME_DAY	NOTETIME1	NOTETIME2	NOTETIME3	NOTETIME4	NOTETIME5	NOTETIME6	NOTETIME7) (: datetime16.);
 format                UNIT_STARTTIME_DAY	UNIT_ENDTIME_DAY	NOTETIME1	NOTETIME2	NOTETIME3	NOTETIME4	NOTETIME5	NOTETIME6	NOTETIME7 datetime.;
 cards;
1234	24Jul18:04:19:00	24Jul18:23:59:59	24Jul18:02:35:00	24Jul18:08:42:00	24Jul18:22:58:00	.	.	.	.
1234	25Jul18:00:00:00	25Jul18:23:59:59	.	.	.	25Jul18:03:25:00	25Jul18:08:18:00	.	.
run;
data WANT; 
set HAVE;
  array NOTES    [*] NOTETIME: ;
  array NOTEP    [7] ;
  array NOTETIME [7] NEW1-NEW7;
  format NEW: datetime.;
  POS=1;
  do I=1 to 7;
    if UNIT_STARTTIME_DAY <= NOTES[I] <= UNIT_ENDTIME_DAY then do;
      NOTEP[I]=1;
      NOTETIME[POS]=NOTES[I];
      POS+1; 
    end;
  end;
  TOTAL_NOTES=sum(of NOTEP1-NOTEP7);
run;
proc print noobs; 
  var PAT_ENC_CSN_ID NEW:; 
run;

PAT_ENC_CSN_ID	NEW1	NEW2	NEW3	NEW4	NEW5	NEW6	NEW7
1234	24JUL18:08:42:00	24JUL18:22:58:00	.	.	.	.	.
1234	25JUL18:03:25:00	25JUL18:08:18:00	.	.	.	.	.
