Finally, some one has explained the use of pragma!!

In some compilers there may be
	#pragma ident "string"
to add interesting information into a special place in the object
and a 
	#pragma debug
to cause the compiler to add special symbols for use by the
debugger and
	#pragma optimize off
to tell the optimizer to stop optimizing the code for a while

In each of the cases the program itself will not change behavior,
but the object file could be larger or the program could run slower.

The pragma
	#pragma inline
could mimic the C++ inline function construct and is technically legal
but gives me a bit of a qualm.
