Thanks guys.

When i write a new mode from the ground up (not using derived-mode or
generic mode), how do i go about defining the syntax table?

For example, i'm writing a mode for the LSL language, which uses a
sytax like C/Java.

So, i start by copying example from text-mode:

(defvar text-mode-syntax-table
  (let ((st (make-syntax-table)))
    (modify-syntax-entry ?\" ".   " st)
    (modify-syntax-entry ?\\ ".   " st)
    ;; We add `p' so that M-c on 'hello' leads to 'Hello' rather than
'hello'.
    (modify-syntax-entry ?' "w p" st)
    st)
  "Syntax table used while in `text-mode'.")

In my case, the LSL is basically ascii based lang. So, do i go thru
each printable ascii char, and add a modify-syntax-entry for it using
the above template?

Another question... i tried to study syntax table, which is a char
table, which is a specialized vector with extra things ... not so easy
to understand... but looking at the syntax table for text mode, it has
some 800 entries. Is a syntax table meant to cover all unicode char?

(am avoiding copying from c mode's syntax table for the moment so i
get more understanding by doing more from the basics... the cc-mode
source seems much complex to dig ...)
