STRUCT - allocate space for a structure.

Usage:

[NAME,NAME,...]:  struct  SIZE,OFFSET

Where:

[NAME,NAME,...]: gives one or more names to be associated with the beginning of the structure.
SIZE: is the size of the structure (in words).
OFFSET: is the (word) offset between the present location of the IC and the beginning of the IC. For example, an OFFSET of 10 indicates that the structure begins ten words beyond the current location.

Description:

"struct" reserves space for a structure with the given SIZE at the given OFFSET. By default, the structure is initialized to all 0-bits, but the "field" macro can be used to allocate and initialize specific fields within the structure.

A structure will always begin on a word boundary, regardless of the offset mode of the current section.
