     The ORG statement

     Normally, SB generates all code so it occupies sequential addresses on
     the target machine, starting at the address named CODEBEG.  You can
     think of this range of addresses as SB's original code section.

     If necessary, you can force SB to compile code at other addresses, by
     using the ORG statement.  The ORG statement takes one of three forms:

          org                or
          org  code                or
          org    code

     where is the address where you want subsequent SB code to
     compile.  You can think of these other address ranges as alternate
     code sections.  For example:

          org  $200

     causes subsequent SB code to compile in an alternate section, starting
     at address $200.  SB will continue to compile all code into sequential
     addresses, until you end the program or change the compile origin with
     another ORG statement.

     If you use the keyword CODE as the argument to an ORG statement, SB
     resumes compiling at the last address in the original code section.

     Perhaps a larger example will clarify this.  Assume that the following
     program was compiled with a CODEBEG address of $8000:

          n = 14              ' this code compiles at $8000

          org  $400           ' change the origin
     table1:                  ' use a label at new origin
          datab  0,1,2,3      ' this code compiles at $400

          org  $500           ' change the origin
          interrupt $fff0     ' RTI ISR compiles at $500
          end                 ' bogus ISR, just for example

          org  code           ' return to original code section
          j = addr(table1)    ' sets j to $400


     You may use as many ORG statements, and change between alternate code
     sections and the original code section, as often as you want.

     In rare cases, you might need to change the address of SBasic's code
     section inside your program.  Early versions of the 68hc912b32
     contained an on-chip bootloader that took over the vector area.  To
