#ifdef DEBUG

// Turn on assertion checking whenever debugging
#define ASSERTS 1

// debug macro - provides a clean way of inserting debugging code without
//  having the distracting #ifdef DEBUG ... #else ... #endif directives
//  interspersed throughout the code.  It also provides an easy way
//  to turn them off with no loss of efficiency.  It is not limited
//  to printf() commands; any code may be inserted.  Variables
//  needed only by the debugging code can be declared inside a
//  debug { ... } statement.
//
// usage:
//      debug <statement>
//  or,	debug { <statements> }
// If DEBUG is on, map "DEBUG_CODE" to nothing!
// This results in the <statement> being executed normally

#define DEBUG_CODE

#else
// If DEBUG is off, map "DEBUG_CODE" to something harmless.
// The clever hack used here is to use a conditional with a
// constant condition, which is optimized out by the compiler,
// so that <statement> is not present in the compiled code!
