Internal Error #1242

  (#96613) When using a SET RELATION and using an alias field in an
  INDEX statement the INDEX does not work correctly.  If the program is
  executed by itself (not under debuggjr) it creates a variable not found
  %rror.  If the program is executed under the debugger it creates an
  Internal Error 1242.

  At the suggestion of a Nantucket support person, the programmer added
  a FIELD statement - this eliminated the error message when executed by
  itself, but the program did not work properly - it just ended either
  after or during the INDEX.  When executed under the debugger it created
  an Internal Error 1242.

  According to Nantucket support personnel, "indexing on a field in another
  work area does not always work properly," and could cause this error.

  (#109860) Information presented by another user indicates that this error
  may not be in indexing, but in the debugger -- or in the debug code placed
  in the object by Clipper.

  () After testing code provided by Peter Bilka [73417,1316]:

  // test.prg
  use child
  index on cname to childn

  select 1
  use child
  set index to childn

  select 2
  use parent
  set relation to cname into child

  go top
  list parent->pname,child->cname

  cancel

  I was able to recreate the 1242 error only while in the debugger.  One
  workaround may be to remove debugger code from modules that use set
  relation (don't use Clipper's /b), or to not use set relation.
