Informix Error -22620

-22620 Host object host variable not declared.

This message indicates an IBM Informix ESQL/FORTRAN preprocessor error. An SQL statement contains a host variable that has not been declared. Host variables are declared in the same way as other FORTRAN variables except that the declaration must be contained in a declaration block between a pair of EXEC SQL BEGIN DECLARE SECTION and EXEC SQL END DECLARE SECTION statements. You cannot use the SQL data types to declare host variables. You must specify a FORTRAN data type or one of the IBM Informix ESQL/FORTRAN data types when you declare a host variable. The data type of the host variable should reflect the data type of the database column to which it corresponds.
