Operator # (Preprocessor Stringize)operator

Preprocessor operator to convert macro arguments to strings

Operatorsoperatordocumented

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.
