Include-file names with double quotation marks

You can use double quotation marks to specify include-file names in the INCLUDE directives, when you set the precompiler option COMPATIBILITY_MODE to ORA.

In the following example, an INCLUDE directive was used with double quotation marks:
EXEC SQL INCLUDE "abc.h";
You can use only single quotation marks without setting the precompiler option COMPATIBILITY_MODE to ORA.
