I want to Concatenate Date & Character Variables

[RADAGBE9]

I have the following dataset:

data Have;
input date mmddyy10. c1$ c2$ c3$  c4 c5;
format date mmddyy10.;
cards;
01/02/2019 A B C 4 5
01/03/2019  4 5 6 7 8 
01/04/2019  3 6 7 8 1
;run;

I want to add a new character column which concatenates column1, column2 & Column3 as:
01/02/2019AB
01/03/201945
01/04/201936

newvar = cats(put(date,mmddyy10.),c1,c2);
