Varying - Inz mandatory?

["Bartell, Aaron L. (TC)" <ALBartell@xxxxxxxxxxxxxx>]

I have a couple VARYING questions.

Question #1.

D error           DS                  Qualified
D  code                         10A
D  description                 256A   Varying
 /Free

  If error.description <> ' ';
    error.code = '0';
  EndIf;
  *InLR = *On;

 /End-Free  

I get a 'Length of varying length variable is out of range.' error message
if I don't Inz the error DS or the description subfield.  This wouldn't be a
problem if in the documentation they said that you needed to Inz
DS's/subfields if they have VARYING fields.  At least I can't seem to find
where it might state that, and I have looked both in the WDSc docs and Info
Center. Do you have to Inz or occupy a field before you can check to see if
it contains a value?  I am on V5R1.  


Question #2
If I define two fields defined as this. . .

D temp        D           256A   Varying
D temp2       D         32767A   Varying

If both fields contain the value 'Hi there' is temp2 taking up more space or
processing than temp?  Or doesn't it matter anymore now that I have VARYING
specified on each field?

TIA,
