As quoted from <607@geac.UUCP> by len@geac.UUCP (Leonard Vanek):
+---------------
| However, for us SQL users there is another problem. Can a C++
| program be passed through the various SQL preprocessors? If yes,
| the key word "delete" in a C++ program will confuse the SQL
| preprocessor. If not, the SQL code may have to be segregated in C
| subroutines in order to preprocess it, and the problem of the two
| deletes goes away because no source code ever goes through both
| the C++ compiler and the SQL preprocessor.
| 
| Does anyone else have thoughts on this problem? Note that I have
| added comp.databases to the distribution list.
+---------------

Informix ESQL/C won't... providing that C++ will accept the generated C
code.  ESQL/C consists of statements from a $ in column 1 to a semicolon;
it only scans from a $, so variables to be known to ESQL/C have to be
declared with

$ long n ;

or similar.  Thus, fancy C++ types probably can't be made visible to ESQL/C.
The generated code still has "delete" in it, but in a quoted string.

Note:  I only know this much from analyzing ESQL/C intermediate code from
Informix-4GL.  It's the only way I can explain the code I see generated.
Any ESQL/C gurus want to comment?
