Expressions:
The expressions used in assignment can return any of the types you can declare variables. Also they might return fail or null. An expression returning fail will not result in any action being taken. Fail is returned when you request a field from a null pointer, or the like.
Example:
dilbegin foo();
var
myvarsl : stringlist;
myvars : string;
myvarint : integer;
myvaredp : extraptr;
myvarunit : unitptr;
code
dilend
