You can declare SQLCA anywhere in the application program where a COBOL variable can be declared. The scope of the structure follows COBOL scoping rules.
If you declare SQLCA, SQLCODE, or SQLSTATE within your file, each variable must be in scope for all executable Embedded SQL statements in the file. The precompiler generates code to set each of these status variables for each Embedded SQL statement. So, if the variables are not in scope, the generated code will not compile.
