type c to short

Hi,

I've defined this:

data:  begin of i_linea OCCURS 0,
   linea(200) type c.
     data: end of i_linea.

...
concatenate '"' i_etq '","' i_pidi '","' pmat-low '","' i_pnet "' into i_linea.

And If I write a string shorter than 200 chars inside this variable, I don't know why the text saved is not full.

Can anybody help me?

Thanks in advance.

Regards.
