Another way to comment code
Post by Michael Hutton on Apr 28^th, 2009, 06:47am

Another way to comment sections of code which people might like, rather than using REM or *| (also *| is not removed when compiled) is this:

:\
\\ you must start the commented area with :\
\\
\\ You can add multiple lines of comment
\\ like this
\\
\\ and this
\\
\\
\\
\\
\\ (you can't leave blank lines)
\\
\\ and you must end with a single backslash
\

I don't know if this commentry is removed by the compiler though.

You can also comment your ASM code by inserting

Code:

;\ A comment

or a block of comments with:

Code:

;\ Commentry
;\ More comments
;\ And more....

I haven't yet checked that the 'compile' option ignores these comments but I it does 'compile' with no errors.

Do remember, though, that an assembler comment ends at the next colon (for some strange reason known only to Acorn) so what you suggest is potentially misleading because there could be more assembler statements on the same line (which will be rendered in green by the editor).

Ah.

Indeed:
Code:

        ;\ a comment : inc dword [^A%]

compiles correctly but is misleading. So this form should be avoided.
