@Richard Mitchell.
I can't tell you how much I object to this. (I'm not being aggressive, honest!)
There is no "proper extension" for a shell script. Run "file /usr/bin/* | grep -i shell" to see a list of o/s built in shell scripts. Then run this:
file /usr/bin/* | grep -i shell | awk '$1 ~ /\.sh/'
Exactly 3 of them (on my Ubuntu system) have the extension ".sh".
This is a (silly) windowsism, where file-extensions matter. Now, Unix does sometimes care. The C compiler, for instance expects source in .c and headers in .h. But, or course it produces executables with no .exe extension. For a shell script, it's the #! line which tells the kernel to run it in a shell, and magic numbers for other types (which is all the same thing, and how "file" works).
I do like the idea of copying (I'd link) the .sh version to a bin/<filename> version, but let's not propagate this daft idea of filename extensions mattering to the os.
You can still grep:
If you can't remember how a case statement works:
grep case $(file * | awk '/shell/ 'print (substr($1,length($1)-1)') (# to get rid of the colon - and I've not tested that specific line, but it's something I do occasionally.) This is proper use of Unix, not demanding file extensions. Unix is great, but it's expert-friendly, and not as windows claims to be "user" friendly.
Sorry to rant, but it's important to me - and you might guess where I stand on systemd :-)

Hello Christian,
Thanks for the help. It is actually a Bash script with filename FireTIG (without .sh extension) I made myself. Where can I find the syntax file for Bash?

Please try the syntax files for sh.vim available at:
http://www.drchip.org/astronaut/vim/index.html#SYNTAX_SH (v154).

As a pointless programming tip, I put the proper extension on my script code files (.sh, .pl, etc) and then use make to copy&strip the extension/chmod them into a bin area. While this seems unnecessary, besides making it easier for vim know how to colorize the code, it also allows the use of find/grep for searching.

I write a function like this:
function InsertNumber(start, end, step)
let i = a:start
let curr_line = 0
while i <= a:end
if a:step <= 0
echo "Error: step cannot <=0."
break
endif
call append(curr_line, i)
let i += a:step
let curr_line += 1
endwhile
endfunction
when I call this function, I type this:
:echo InsertNumber(8,10,1)
8
9
10
1) How can I give arguement "step" a default value(eg: 1) when define the function?
like a C function:
void C_func(int a, int b_have_default_val = 1)
{
;
}
2)
I want to print number like this, how to do it?
08
09
10

you can use optional arguments like this
function InsertNumber(start, end, ...)
if a:0 == 0
let l:step = 1
else
let l:step = a:1
endif
...
endfunction
> 08
> 09

Use the printf() function:
call appendline(curr_line, printf('%02d', i))
Or if your numbers can have more than two digits:
let width = trunc(log10(a:end)) + 1
let format = '%0' . width . 'd'
call appendline(curr_line, printf(format, i))

I complete the function as follow, now I want to add radix option, but I don't know how to get width. Can you help me complement it
function InsertNumber(start, end,...) " step,is_column_first_0_padding,radix(b,d,o,x)
let l:i = a:start
let l:curr_line = 0
if a:0 == 0 " a:0 extra argument numbers
let l:step = 1
else
let l:step = a:1 " the first extra argument
endif
if a:0 == 2
let l:is_padding = 0
else
let l:is_padding = 1 "default padding
endif
if a:0 == 3
let l:radix = a:3
else
let l:radix = ""
endif
if l:radix == "b"
elseif l:radix == "o"
elseif l:radix == "x"
else
let l:width = float2nr(trunc(log10(a:end))) + 1
let l:format = '%0'.l:width.'d'
endif
while l:i <= a:end
if l:step <= 0
echo "Error: step cannot <= 0."
break
endif
if l:is_padding == 1
call append(curr_line, printf(l:format, l:i))
else
call append(curr_line, l:i)
endif
let l:i += l:step
let l:curr_line += 1
endwhile
endfunction

there is an simpler way to calculate the necessary width -- just count
the number of characters used for the a:end parameter when printed:
let width = strlen(printf('%d', a:end))
This can also be used to calculate the width for other radices than 10:
if l:radix == "b"
let width = strlen(printf('%x', a:end)) * 4
elseif l:radix == "o"
let width = strlen(printf('%o', a:end))
elseif l:radix == "x"
let width = strlen(printf('%x', a:end))
else
let width = strlen(printf('%d', a:end))
endif
Note that there is no specification for output as a binary number in
printf().

Jürgen

let l:step = get(a:000, 0, 1)
Other arguments are to be handled in a similar fashion.
> else

let l:radix = get(a:000, 2, 'd')
(needed for the below suggestion).
> elseif l:radix == "x"
> else

let l:width = len(a:end)
For other radix variants you will have to use printf indeed.
I could even suggest
let l:format = '%0*' . l:radix
let l:width = len(printf('%' . l:radix, a:end))
(note: no if's at all).
> let l:format = '%0'.l:width.'d'
let l:format = '%0*d'
> echo "Error: step cannot <= 0."

This is wrong place to check, l:step does not change, but you check it
constantly. Move all arguments checks just below the place where you
define arguments.
> if l:is_padding == 1
> call append(curr_line, printf(l:format, l:i))
call append(curr_line, printf(l:format, l:width, l:i))

I tried to pass a count to <F11> but got a range error.
nmap <F11> :call VMA()<bar>:bn<cr>
Can it be done?
nmap <F12> :bn<cr>
4<F12> works

in my experience counts and mappings don't work together very well. A
preceding count is always used for the first command in the mapping only.
So what happens when you enter
4<F11>
is that Vim converts your count to an address for the command-line,
which effectively results in
:.,.+3call VMA()|:bn
In your mapping you first have to remove this address and "move" the
count to the front of the command :bn. The count is stored in the global
variable v:count. There is an example at :help v:count which can be
adopted:
:nmap <F11> :<C-U>call VMA()<bar>execute v:count1 . "bn"<cr>
Note that I removed the superfluous second colon and that instead of
v:count I used v:count1 which defaults to 1 if no count was given.

Jürgen

More reading... a count is not needed.
First time I have used bufdo!
function! B_() " field delimiter ';'
g/^\d*;\+$/d " remove blank records
v/^\d\+;/d " remove non-data records
let @4=expand('%:t:r') " remove path, extension
let @4=substitute(@4,'\s\+',' ','g') " remove extra whitespace, normalize
let @4=substitute(@4,'^ ','','') " remove leading whitespace
let @4=substitute(@4,' $','','') " remove trailing whitespace
let @4=substitute(@4,'.*\zs ',';','') " replace ' ' ';' before date
let @4.=";" " append ';' filename;date
g/^\d\+;/:normal "4P " prefix lines filename;date;
endfun " example :bufdo call B_()
function! B() " everyone keep quiet
silent bufdo call B_()
endfun " example :call B()
