Syntax for declaration of a DUT:

TYPE <identifier> : <DUT components declaration>

END_TYPE

The DUT components declaration depends on the type of DUT, e.g. a structure or an

enumeration.

Example:

See in the following two DUTS, defining structures struct1 and struct2; struct2 extends

struct1, which means that you can use "

struct2.a" in your implementation to access

variable a.

TYPE struct1 :

STRUCT

a:INT;

b:BOOL;

END_STRUCT

END_TYPE

TYPE struct2 EXTENDS struct1 :

STRUCT

c:DWORD;

d:STRING;

END_STRUCT

END_TYPE

1 2 ... 77 78 79 80 81 82 83 84 85 86 87 ... 116 117
