** PURPOSE: This sample program demonstrates the use of static SQL.
**          It will output the entry in the FIRSTNME column where
**          the entry in the LASTNAME column equals "JOHNSON".
**          Otherwise, an error message is printed.
**
** An external function "check_error" is contained in the file "util.c"
** which must be compiled along with this file.  
**
**    EXTERNAL DEPENDENCIES :
**       - Ensure existence of database for precompile purposes.
**       - Precompile with the SQL precompiler (PREP in DB2)
**       - Bind to a database (BIND in DB2)
**       - Compile and link with the IBM Cset++ compiler (AIX and OS/2)
**         or the Microsoft Visual C++ compiler (Windows) 
**         or the compiler supported on your platform.
**
** For more information about these samples see the README file.
