Cause: This error occurs when a
cursor-attribute (%FOUND, %NOTFOUND, %ROWS, %IS_OPEN, etc.) appears
following an identifier that is not declared as a cursor or cursor variable.
It occurs, for example, if the variable name my_cur in my_cur%FOUND was not
properly declared as a cursor or if the variable declaration was placed
incorrectly in the block structure.
Action: Check the spelling and
declaration of the identifier. Also confirm that the declaration is placed
correctly in the block structure.
