With {$h+} it works.

But when having pchar I wonder why it generally is not possible to make 
strings longer than 255 as it was possible in the previous compiler version.

For shortsting I accept strings not longer than 255 chars.

Why is it not possible to make a var like
svar : shortstring[ 20 ] ?

The whole program I made is compiled with {$h-} so it would be much 
fault-prone work to put everywhere {$h+} and then {$h-} again.
