Fully generic types are
DATA and ANY
Generic type SIMPLE is for
Elementary data types or flat structures
There are two ways to type generic object refferences. What are they
Type ref to object
Type ref to data
The two numeric generic types are
DECFLOAT and NUMERIC
The two character like generics are
CLIKE and CSEQUENCE
The single generic hex type is
xsequence
What are the two variants of CASTING
If the type is defined FIELD-SYMBOLS TYPE mystruct. ASSIGN mydata to CASTING. If the field symbol is type ANY ASSIGN mydata to CASTING TYPE MYSTRUCT
What is the only statement which can dereference a generically typed reference variable
Assign fld1->* to
