Parsing Strings?

Okay, I'm working on a thing that copies what you say using prims. I want to know how to parse the string message down to the 1st letter, then just the 2nd letter, then the 3rd. etc,etc. I'm not sure how I would do this, any help?

The lslwiki.com is scripter's best friend...

Use llGetSubString(). That function takes a string and returns the specified section of it. The wiki explains it well, but basically you'll do something like:

integer x = 6; // position in the string to check, starting at zero
string sentence = "Hello Avatar!"; // the string to scan
string letter = llGetSubString(sentence, x, x);

letter will become "A", the 6th position within the string.

if you can afford to use a list ...

list data;
default
{
    state_entry()
    {
       llListen(27,"",llGetOwner(),"");
    }

    listen(integer channel, string name, key id, string message)
    {
       integer total = llStringLength(message);
       integer x;
       while (x < total)
       {
           data += llGetSubString(message,x,x);
           ++x;
       }
       
       llOwnerSay(llDumpList2String(data,"^"));
    }
}

just dont forget to clean out the list once your done using the data (data = []; )

Whilst Osgeld's approach will work, and is possibly the best bet for things of random length (parsing sentences into words say, although you can nibble that with the string functions too depending on what you want to do with it) I'd go with the llGetSubString() approach.

I *like* lists. I use them probably more often than needed. For that specific application, I'd still use llGetSubString(). It is, however, good to know about llParseString2List as well, there are times when nothing else will do.
