++MESSAGE
++MESSAGE message
The compiler directive ++MESSAGE message simply outputs a literal text message to the screen during compilation. This is generally useful in conjunction with Conditional Compilation (in which see Example 2) to give the programmer visual confirmation that the conditions are being interpreted as intended, or to warn of unusual or questionable environmental conditions. The remainder of the line following the keyword ++MESSAGE is output literally, as-is, to the screen, without any regard to punctuation or delimiters. Example:
++MESSAGE This is an example of a compiler message
