OPEN USING followed by FOREACH

With Genero BDL, avoid having an OPEN ... USING instruction.

In earlier versions of IBM® Informix® 4GL (I4GL), the FOREACH instruction had no USING clause to pass SQL parameters to the prepared statement. SQL Parameters could be specified in a OPEN USING instruction, and were re-used by the next FOREACH instruction:
PREPARE st1 FROM "SELECT * FROM tab WHERE col>?"
DECLARE cu1 CURSOR FOR st1
OPEN cu1 USING var 
FOREACH cu1 INTO rec.*
  DISPLAY rec.*
END FOREACH

This feature is supported by Genero Business Development Language, but can lead to defects with some versions of the Informix database client. Review your code to avoid the OPEN statement by moving the USING clause to the FOREACH instruction.
