China DOS Union

I have a relatively large text as follows:
//@Function name: abs
//Function prototype: int abs(int x);
//Function purpose: find the absolute value of integer x
//Function return: calculation result
//Parameter description:
//Header file: <math.h>,<stdlib.h>
//Usage example:
#include <stdio.h>
#include <math.h>
int main()
{
int number=-1234;
printf("number: %d absolute value: %d",number,abs(number));
return 0;
}


//@Function name: fabs
//Function prototype: double fabs(double x);
//Function purpose: find the absolute value of x.
//Function return: calculation result
//Parameter description:
//Header file: <math.h>
//Usage example:
#include <stdio.h>
#include <math.h>
int main()
{
float number=-1234.0;
printf("number: %f absolute value: %f",number,fabs(number));
return 0;
}




//@Function name: sin
//Function prototype: double sin(double x);
//Function purpose: calculate the value of sinx. Sine function
//Function return: calculation result
//Parameter description: the unit is radians
//Header file: <math.h>
//Usage example:
#include <stdio.h>
#include <math.h>
int main()
{
double result,x=0.5;
result=sin(x);
printf("The sin() of %lf is %lf",x,result);
return 0;
}
.........

I want to use the text before each "//@Function name" as the boundary, and split each C-language function description into a separate text file named after the function name.
Since there are quite a lot of them, I want to do it with a batch file, but I don't know how to start. Hope an expert can give me some pointers?

The VBScript from the poster above is pretty good. I tried it, and it works. But I wonder whether this kind of thing can be done with a DOS batch file. DOS is more fundamental, and I want to learn through actually using it. Thanks.

@echo off&setlocal enabledelayedexpansion for /f "tokens=1*" %%i in (test.txt) do ( set var=%%i set str=%%j if "!var:~3,4!"=="函数名称" (set lxm=%%j&>>!lxm!.txt echo !var! !str! ) else ( >>!lxm!.txt echo !var! !str! ) )
The format is changed slightly, mainly the spaces.

Posting the code written by brother 9527 on his behalf; it matches the code format the OP wants very well.
@echo off&setlocal enabledelayedexpansion for /f "tokens=1* delims=@" %%a in (test.txt) do ( if "%%a" equ "//" ( call:P "%%b" ) else ( >>!a! echo %%a%%b ) ) goto:eof :P for /f "tokens=1* delims=: " %%x in (%1) do set a=%%y.txt&>>!a! echo %%a%%b goto:eof

The code from jmz573515 and the code posted on behalf of ccwan achieved the same effect.
Really different tunes played with equal skill. Looks like I still have a long way to go in learning: "The road ahead is long and has no ending; yet high and low I will search with my will unbending...
