Concatenating variables that contain only zeros

I'm trying to concatenate all variables in a dataset into a singular variable, however some of the input variables contain only zeros. When using the CAT procedure these zero filled variables are removed. However, I need to retain these zeroes within the final variable. Additionally, I do not want to put any delimiters within this variable.

Re: Concatenating variables that contain only zeros

Are all the variables type defined as alphanumeric or are some of them numeric.

Numeric variables are usually displayed with leading zeros suppression.

In order not to suppress leading zeroes use format z9,  where 9 define the length of desired variable for concatenation:

      assume x='ABC';   /* alphanumeric */

                     y = 25;     /* numeric */

       result = cat(x, put(y,z5));      /* = ABC00025 */

Hi Shmuel, all the variables are numeric.

Zeroes wouldn't be removed, but missing would be. Verify if the data is missing or 0. 

 

If missing(variable) then ...

Re: Concatenating variables that contain only zeros

What is the use of concatenating numeric variables ?

 

You still need to decide how long is each variable.

       v1 = 12345;  v2=33;   v3=7;

       v1=  6789;    v2=120;  v3=99;

 

      result = put(v1,z6.) || put(v2,z4.) || put(v3,z2.);

Re: Concatenating variables that contain only zeros

A very basic item in requesting suggestions is to provide an example of your starting data and the desired result for that data. It need not have as many variables or observations as you have but enough to show an example and clarify your description. Without concrete values we're guessing somewhat as to what your result would be.
