Create a variable with counts from existing categorical values

[rsva]

Greetings,

I have a data with 5 columns for each partner, test results for each partner (POS1-POS5 if positive, NEG1-5 for negative results). Te last set of columns is age group of that partner. Snap shot of my data below.

Partner1	Partner2	Partner3	Partner4	Partner5	POS1	POS2	POS3	POS4	POS5	NEG1	NEG2	NEG3	NEG4	NEG5	Age1	Age2	Age3	Age4	Age5
1	0	0	0	0	1	0	0	0	0	0	0	0	0	0	10-15	10-15	16-20	21-25	50+
1	1	0	0	0	1	0	0	0	0	0	1	0	0	0	16-20	21-25	50+	10-15	10-15
1	1	1	1	0	0	0	1	1	0	1	1	0	0	1	21-25	50+	10-15	50+	50+
1	1	0	0	0	0	0	0	0	0	1	1	0	0	0	10-15	10-15	16-20	21-25	50+

I am trying to create a count of how POS and Neg by age group.

e.g.If there is

1 partner with age A1 then #A1=1, A2=0, A3=0, A4=0

2 partners with A1 and A3 then #A1=2, A2=0, A3=1, A4=0

3 partners with A1, A3, A4 then #A1=3, A2=0, A3=2, A4=1

4 partners with 2 in A1, 2 in A4 then #A1=5, A2=0, A3=2, A4=3

Snapshot of my final output:

	POS	NEG
Age1
Age2
Age3
Age4

I used SUM (of POS1-POS5) and SUM (of NEG1-Neg5) to get no. of positives and negatives. But not sure how to proceed with POS and NEGs by age group.

THanks in Advance.

Just how does this differ from your other extremely similar question in

https://communities.sas.com/t5/SAS-Programming/Get-counts-by-groups-across-columns/m-p/748548

And have you read any of the responses to that one and asked questions if you didn't understand.
