Doron,
You could try something like this:
*-- create some test data
CREATE CURSOR CursorA (aaa C(10), bbb C(10))
CREATE CURSOR CursorB (ccc C(10))
FOR i=1 TO 100
	INSERT INTO CursorA VALUES("aaa"+ALLTRIM(STR(i)),"bbb"+ALLTRIM(STR(i)))
ENDFOR &&* i=1 TO 100
FOR i=1 TO 100
	INSERT INTO CursorB VALUES("ccc"+ALLTRIM(STR(i)))
ENDFOR &&* i=1 TO 100

*-- create combined cursor
CREATE CURSOR CursorC (aaa C(10), bbb C(10), ccc C(10))

GO TOP IN CursorB
SELECT CursorA

SCAN
	SCATTER MEMVAR MEMO
	SELECT CursorB
	SCATTER MEMVAR MEMO
	SKIP IN CursorB
	INSERT INTO CursorC FROM MEMVAR
ENDSCAN
