Operator # (Preprocessor Stringize)

Preprocessor operator to convert macro arguments to strings

Syntax
	#macro_argument

Description
	This operator converts the macro_argument into a string whose value is 
	the name of the argument. This substitution is made during the macro 
	expansion, previous to compilation.

	Note: because of this feature, care should be taken when using 
	file-handling statements in a macro.  Because of potential ambiguity 
	with file-handling statements that take a "#filenum" parameter, if 
	filenum is one of the macro parameters, it may be necessary to wrap the 
	filenum expression in parenthesis (e.g. "#(filenum)"), to separate it 
	from the # sign.  Otherwise, filenum will be stringized in the macro.

Example
	#define SEE(x) Print #x ;" = "; x
	Dim variable As Integer, another_one As Integer
	variable=1
	another_one=2
	SEE(variable)
	SEE(another_one)

Output:

	variable = 1
	another_one = 2
