Repeating generated in array

[Mscarboncopy]

I am using an array to create a variable I need - variable A.

When I do this, I need to keep certain variables B C D E F G, so I can have them in my final data file.

All of these are character vars except G (numeric var)

However, when I create this file with the array - these extra variables are repeating to fill in blanks - Since new variable A repeats for each ID. The missing in this file are okay. All I need is for the data from these extra variables to be in the first  row of the ID, not all of them. Could I add something to the array to make this happen? Or is there any other way I can do this after the data want is created? Thank you.

Data want (keep= ID A B C D E F G);
set have;
array _pres {*} pres: ;
do A=1 to dim(_pres);
if _pres{A}>0 then output;
end;
run;

What I am getting:

ID A         B             C          D                  E                  F            G

1  2    descript1       .           descript3      descript4          .          1

1  9    descript1        .          descript3      descript4          .          1

1  12  descript1       .           descript3      descript4         .           1

2  10    .                descript2     .             descript4    descript5    .

3   33 .                      .               descript3     .            .                 .

what I need:

Data want (keep= ID A B C D E F G);
set have;
by ID;

if not first.id then call missing(B, C, D, E, F, G);

run;

Try this:

Data want (keep= ID A B C D E F G);
set have;
by id;
if not first.id then call missing(b,c,d,e,f);
run;

If that's not it, then please provide your original data (in your data set named HAVE) as SAS data step code (instructions).

Thank you. That is it.

Post the code and log.

Sorry. I got the error because I didn't add the commas. I meant to edit my answer but it took awhile to get through. Thank you!
