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;
CHARACTER*5 SQLSTATE
INTEGER SQLCOD
.
.
.
EXEC SQL END DECLARE SECTION
If neither of these is specified, the SQLCOD declaration is assumed during the precompile step. The variable named 'SQLSTATE' may also be 'SQLSTA'. Note that when using this option, the INCLUDE SQLCA statement should not be specified.
For applications that contain multiple source files, the declarations of SQLCOD and SQLSTATE may be included in each source file as shown above.
