  ****************************************************************
  The ZONECHECK processing was incorrectly identifying some data
  items as senders when they were not.  When the ZONECHECK
  compiler option is in effect, the compiler was incorrectly
  generating a NUMERIC class test for data items passed BY
  REFERENCE in CALL statements.  BY REFERENCE data items could be
  senders or receivers, but the compiler decided that they were
  senders.  It is perfectly legal to have these data items be
  receivers only. In the case of the UNSTRING statement, a
  NUMERIC class test was incorrectly being generated for the data
  item used in the COUNT IN phrase, even though that data item is
  a receiver only, not a sender.
  

Problem conclusion

• The compiler was updated so that a NUMERIC class test is no
  longer generated in the following two scenarios: 1. a data item
  passed BY REFERENCE in a CALL statement 2. a data item used in
  the COUNT IN phrase of an UNSTRING statement.
