.b 3
The STRUCTURE macro:
.b
.lt
	struct	example
		data-statements
	end
.el
.b
is equivalent to:
.b
.lt
	psect example_abs <ABS>
		data-statemens
	end
.el
.b
If ^&psect-name\& is specified, then ^&psect-name\& will be the .PSECT name;
otherwise, the name of the record appended with the string "_abs" will be the
psect name. 
.b
For every STRUCT macro specified, a corresponding END macro must also be
specified. 
.b
For example:
.b
.lt
	struct	uic
	  union
	    map
		uic.member: 	.blkw 1
		uic.group: 	.blkw 1
	    end
	    map
		uic.longword: 	.blkl 1
	    end
	  end
	end
.el
.b
