Hi people!
I Want to declare some host variables with global scope. Like this C variable:
MyFile.h
...
    char str_var[20];
...

But i can't put SQL sentences in a include file. And if i do this:
MyFile.pc
...
    EXEC SQL BEGIN DECLARE SECTION;
         char str_var_h[20];
    EXEC SQL END   DECLARE SECTION;
...

... i can't see this variable from others sources, although I declare it like 'extern'.
Probably it's very easy to solve, but i'm really mentally blocked... Can anybody help me, please?
Thanks in advance!!

Hi people!

That's my solution:
MyFile.h
...
    char str_var[20];
...

MyFile.pc
...
    EXEC SQL BEGIN DECLARE SECTION;
         char str_var_h[20];
    EXEC SQL END   DECLARE SECTION;
    void  c_var_to_host();
    void  host_var_to_c();
    /* I call this functions when needed. The C and Host
    variables always will be with the same value */
    void c_var_to_host()
    {  strcpy(str_var_h, str_var);    }
    void host_var_to_c()
    {  strcpy(str_var, str_var_h);    }
...

It's an ugly solution, but it's the first i thought.
Thanks people!
