Update raw output to work with RMB only definitions at the start It seems useful to be able to define a number of symbols at the start of the source file without generating a run of NUL output. This update adjusts the output to ignore any number of statements that generate no output as long as there is a subsequent ORG statement. If there is no ORG statement after them, the NUL sequence should still appear.
