PCC-00026: Invalid host variable "string" at line number in file string
Cause: A host variable used in a SQL statement was not declared properly. Some possible causes follow: It was not declared in the DECLARE section. Its datatype is not supported. Its name is misspelled. It is a COBOL group item; in Pro*COBOL, only elementary items are allowed in a SQL statement.
Action: Add or correct the host variable declaration.
