When using the LANGLEVEL precompile option with a value of SQL92E, the following two declarations may be included as host variables:
EXEC SQL BEGIN DECLARE SECTION END-EXEC. 01 SQLSTATE PICTURE X(5). 01 SQLCODE PICTURE S9(9) USAGE COMP. . . . EXEC SQL END DECLARE SECTION END-EXEC.
If neither of these is specified, the SQLCODE declaration is assumed during the precompile step. The '01' can also be '77' and the 'PICTURE' can be 'PIC'. Note that when using this option, the INCLUDE SQLCA statement should not be specified.
For applications made up of multiple source files, the SQLCODE and SQLSTATE declarations may be included in each source file as shown above.
