Comments
Comments are used to 'comment out' code that you don't wish be used inside your scripts.
;Single line command /* This is a multi line comment and all code between the open comment And the close comment will be 'commented out' */
Commends are used to comment out whole lines, even the multi-line comments are used to commend whole lines, which is the main difference between mIRC's commenting system and most other common languages that use /*...*/
Examples
;Comment line /* This is a comment. */ We're still in a comment since the line above didn't start with */ So it didn't acknoledge it as the end of the comments. */ Since this line did, it is taken as the last line comment line.
Note
As you can see from the above example, commends are generally line based and a commend is used to comment the whole line, including the line to end the comment block. The only exception to this rule is when you start a multi-line commend block from a concatenated line, as illistrated below:
Commands | /* Comment | Comment2 Commands2
In the above example the | is taken as a comment, nothing after the /* is taken as anything other than a comment.
This is where multi-blocks and single line commends differ when it comes to parsing concatenated commands.
Commands | ;Comment | Commands2
