Novice: String inside a string?

Howdy all,
I'm relatively self taught at scripting, and I'm trying to figure out if it's possible to put a predefined string and text inside another string? if it is, can somebody post a short example of how to code it?

Here's a short simplified example of what I'm trying to do. Not posting the entire script because it's massive and the three parts (including where I defined what is inside line7 are difficult to find visually). Basically, I'm trying to define a string that includes both text and strings within it.

string line7;
string text01 = "text"+line7+"text"

I only know how to combine text and string inside the llSay function, and trying to figure out if it's possible to do it or something like it inside a string. Thankyou kindly for any help you have to offer.

duh, I'm a doof. figured it out. ((would delete this if knew how)) the string text01 coding does work, just wasn't putting it into the correct place.

I dont know if this is that you need
Here the code

// www.lsleditor.org  by Alphons van der Heijden (SL: Alphons Jano)

string texT1="A";
integer plusText=0;
integer switch = 0;//Just for on and off

default
{
	state_entry()
	{
		llSay(0, "Im Off and ready");
		llSetTimerEvent(0.0);
	}
	touch_start(integer total_number)
	{
		if (switch==0)
		{   llSay(0, "im On and counting..");

				llSetTimerEvent(5.0);
				switch=1;
			}else if(switch==1)
	{  llSay(0, "Im Off");

			llSetTimerEvent(0.0);
			switch=0;
			texT1="A";//set the string like at the begining
			plusText=0;//set theinteger like at the begining

		}

	}
	timer()
	{
		plusText +=1;
		texT1=texT1+(string)plusText;//this  (string)is for convert first the integer to string first /the texT1=texT1+   -->take your old text update and add teh new text result of the plusText+=1
		llSay(0, "My text is:"+" "+ texT1);

	}
}

Try it and let me know
