Usage
Use the base.TypeInfo.describe()
class method to display the type definition and
values of the program variable passed as argument. Type information and values are written to the
stdout stream.
The method follows the same data formatting rules as base.TypeInfo.create().
Note: The
base.TypeInfo.describe()
method is deprecated. As replacement, use the
base.TypeInfo.create()
method to create an om.DomNode
object, and
produce the XML string with the om.DomNode.toString()
method.Example
MAIN
DEFINE r RECORD
key INTEGER,
lastname CHAR(20),
birthdate DATE,
comment VARCHAR(200)
END RECORD
LET r.key = 234
LET r.lastname = "Johnson"
LET r.birthdate = MDY(12,24,1962)
LET r.comment = " "
CALL base.TypeInfo.describe( r )
END MAIN
Output:
Field type is :
RECORD (4 members)
key:INTEGER
lastname:CHAR(20)
birthdate:DATE
comment:VARCHAR(200)
Field type end.
