Empress C-API MSCALL

SQL commands may be embedded in a "C" program with the routine "mscall". The routine "mscall" takes two  arguments,  the database name and the SQL command.

      mscall (database_name, sql_command);

Both the database name and the SQL command are strings. The strings may be built by the application program. The routine returns zero (0) if the statement succeeds, and a non-zero value if it fails. A failure may be caused by different events such as a syntax error in the SQL command, or an invalid attribute or table name.
