Operator ## (Preprocessor Concatenate)

Preprocessor operator to concatenate strings

Syntax
	text##text

Description
	This operator creates a new token by concatenating the texts at both 
	sides of it.  This text can be recognized by other macros and further 
	expanded.  One use, is to create a macro that expands to different macro 
	names, variable names, and function names depending on the arguments 
	received.

	Note:
		In macro/define's use '##_' to escape line continuation character '_' 
		to allow multiple lines of macro expanded code to be combined into a 
		single statement.

Example
	#define Concat(t,n) t##n

	Print concat (12,34)

	Dim Concat (hello,world) As Integer
	Concat (hello,world)=99
	Print helloworld

	Output:

	1234
	99

Version
	* Before fbc 1.08.0, '##_' did not allow to escape line continuation 
	  character '_'.
