Comments in assembly-mode and tabstops

Comments in assembly-mode and tabstops

[Mark Tilford]

1)  If I want to comment out a few lines of assembly, I tend to:
- Move the cursor to the beginning of the line.
- Push semicolon

Unfortunately, emacs decides to jump to the end of the line (or worse,
sometimes the middle of the line) before putting down the semicolon.
I have to use the method of:
- Move the cursor to the beginning of the line
- Push enter
- Push up
- Push semicolon
- Push delete

This is very annoying.  What's the intended way to comment out code in
assembly-mode (or disable the above behavior)?


2)  I like a two or four space indention on my code.  Unfortunately,
emacs tends to store this as a mix of tabs and spaces.
Is there a way to have emacs handle the combination of, say, a four
space indent and three levels deep stored as three tab characters, and
displayed with the width of 12 spaces?

3)  I'm really used to the behavior of "If a line is wider than the
window, down arrowing only stops once on that line."  Is there a way
to get this behavior back?

Try customizing the variable comment-column, it sounds like you'd like
its value to be zero.

Customize the variable indent-tabs-mode to nil.

Customize line-move-visual to nil.  (This is in NEWS.)

Isn't it the same as all modes? i.e. mark the beginning of the first line,
move down, and type M-;
