I'm not sure the ricoh 5A22 has large enough immediates for it, but there is a easy way to avoid a jump over a small amount of dead memory (example in x86):

  430B  3D -- -- -- --  cmp eax dead32  # only affects flags
  4310  xx              dowhatever

See, eg: http://www.muppetlabs.com/~breadbox/software/tiny/revisit.ht... , where it's used to skip over a mandatory header field.
