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
