Character values have been converted to numeric values when entering .k as a number.

[Filipvdr]

hi,

at my client i have to put .K (which corresponds with not known), .V , .D ... possible in a numeric field. As it begins with a . SAS accepts it.

var&i = .K

But i'm getting this errors... any help?

Please post with code and some example what you want to achieve

[Filipvdr]

underneath my datastep, the result is ok

For example:

AEENMTH is numeric, and has as value K after running the datastep. But I think i'm getting some "Notes" because of that:

Is there a way to rewrite the code, to not get this note?

Datastep:

very simple, = ' ' refers to a character missing value.  You're applying it to a numeric variable, so it is converting the character missing value to a numeric missing value.

You can either change ' ' to . which is the default missing numeric value, or use missing(varname) which applies to both character and numeric variables (and will also pick up special missing numeric values such as .K)

[Filipvdr]

thanks.. did not focused on that part.. though it could be possible that I don't know if the variable is numeric or character...

[Keith]

If you're not sure of the variable type then use the MISSING function, although if you're assigning a new value then you obviously need to know which type to use!

It's not covered in the scope of you question, but your code can be simplified using either of the 2 methods below.  This saves checking for the missing value each time.

if missing(AEACN) then do;

         if _AEACN = 1 then AEACN = .K;         

  else if _AEACN = 2 then AEACN = .V;

  else if _AEACN = 3 then AEACN = .D;

  else if _AEACN = 4 then AEACN = .A;

end;

drop  _AEACN;

if missing(AEACN) then do;

  select (_AEACN);

   when (1) AEACN = .K;

   when (2) AEACN = .V;

   when (3) AEACN = .D;

   when (4) AEACN = .A;

  otherwise end;

end;

drop _AEACN;
