More Information

 You can issue the WHENEVER statement only in precompiled
 programs.  The WHENEVER statement specifies the execution path a
 host program will take when any embedded SQL statement results
 in one of these following exception conditions:

  o  Row not found

  o  An error condition

  o  A warning condition

 For the condition, WHENEVER either specifies that the program
 continue execution or branch to another part of the program.
