Thread: Comment in ECPG - again

    Hi all,

    fine, ECPG doesn't know preprocesor macros as #if, #ifdef... - you
wrote, that this is ok, because this is preprocesor commands.

    But why ECPG know '//' and '/*' and '*/' C/C++ style comments?

    Somebody wrote, that ECPG translate only exec sql commands, not true,
when I write this:
//exec sql ssss

    ECPG don't translate this line => it knows C/C++ comments... - this
construction is wrong, but ECPG doesn't say parse error on this line =>
skips it.

    So, is ECPG only ESQL compiler (translator) or complex translator from
ESQL to C/C++? I think, that ECPG want be complex translator => it may know
also preprocesor directives....

// is also an SQL comment. The backend will parse it correctly too.

/* ... */ was added for convenience. After all this is C code. But #include
is CPP code.

This is not an exec sql command, but a comment.

Please do not mix C/C++ with CPP. After all all CPP commands do not belong
into the C language at all.
