Question

looking how to suppress a warning from the compiler that says possible data loss,

st:= copy(str,0,2);

where st is string[2] and str has more then 2 chars.

and copy is defied as from str return a new string that is a subset from 0 , 2 places.

Answer 1

If you just write:

st := shortstring(str);

The compiler will do the work for you.

It will cut str content to fit the maximum length of st. So if st is defined as st: string[2]; if will retrieve only the 2 first characters of str.

But you may loose non ascii encoded characters in str (not a problem if it does contain only English text).
