The resource initialiser has different forms depending on whether a single, -simple, member is being initialised, or whether a struct or an array is being -initialised:

-<resource-initialiser> -resource-initialiser ::= - <member-name> [ (<length-limit>) ] = <initialiser><initialiser> -initialiser ::= - <simple-initialiser> | <struct-initialiser> | <array-initialiser> -

Resource members may be initialised by default (in the struct definition) -or explicitly initialised (in the resource definition).

In general,

If a member is initialised -in a RESOURCE statement, then that is its value.
If a member is initialised -in a STRUCT statement, then that is its value for all resources -which do not explicitly initialise it.
If a member is neither initialised -in a RESOURCE statement nor a STRUCT statement, -then: BYTE, WORD and DOUBLE members -contain zero; TEXT, LTEXT and BUF members -contain an empty string.
It is an error for LINK and LLINK members -to have no explicit value, so they must be initialised, either by default -(in the STRUCT statement) or explicitly (in the RESOURCE statement).
SRLINK members -may not be initialised (either in the STRUCT statement or -a RESOURCE statement) since they are automatically assigned -the resource id of the resource in which they appear.
Members which are themselves STRUCT s -may not be default initialised. They can only be initialised in the RESOURCE definition. -If they are not explicitly initialised, they will take up zero bytes in the -resource file. For example, given the following STRUCT definition:
STRUCT TEST2 - { - WORD value; - STRUCT tester; - }
The following RESOURCE statement only generates -the two bytes 0xFF 0x00.
RESOURCE TEST2 item - { - value=255; - }
