 `How can I replace a text token by itself, along with some additional text?
 `Example: 
 `EXEC SQL select * from emp;     __curline = 23; EXEC SQL select * from emp;
 `before ^^^^^^^^^^^^^^^^^^^^     after ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 `
 `#define EXEC __curline = __LINE__; EXEC 
 `is not the solution, cpp would try to resolve EXEC recursively

If your preprocessor is non-ANSI, you might try:

	#define EXEC __curline = __LINE__; EX/**/EC 

or something similar. Note that this is very unportable.
