Increment a variable

 Hello,
	I don't know whether this question is stupid question or not?

	How can I achieve following c++ code in XSLT.

	void fun1()
	{
		for(int i=0;i<1000;i++)
		{
		   fun2(i);
		}
	}

	void fun2(int var)
	{
		if ( var == 0 )
		{
			var++;
			// do something
		}
		else
		{
			Var++;
			// do something
		}
		if ( var == 100 )
		{
			Var = 0;
			// do something
		}
	}


Thanks in advance,
