Noob Coding symbol question..

[gohan4]

Just curious...My question is, what do the the Dollar signs and the various other symbols mean in the coding? I have read the manual and alot of the other information and I know nothing about coding, I even did a search on the internet about programming lingo definitions but I can't find anything. The manual just explains how to use them and is pretty vague, it does tell what slashes and some of the others are, but not dollar signs.

Thanks

In my limited understanding, the $ followed by { basically denotes the beginning of an object, like

Code: Select all

${Me.Dumbass}

A { all by itself, on the other hand, denotes that the next line below this statement is a continuation of the same line essentially, example:

Code: Select all

/if (${Me.Dumbass}) {
/kill myself
}

After completing an if statement, always remember to end it with a }

The $ in programming is often, especially here, used to define a "string" for a parameter within the code. Basically, anything that you use to take data in or put data out that is not a numerical function (meaning used for math) is a string.

The example given by A_Druid_00 of ${Me.Dumbass} is a string. The full string is defined by the boundries of the { and } signs.

Oh, and you always MUST keep track of all nesting done, because for each time you open a bracket [ or { you MUST close it as well with its match. If you fail to have an equal number of opening and closing brackets of the same kind you will run into many problems.

I hope this helps.

I would have never expected responses like that from any of you people.

Cheers.

Well, it wasn't the typical "flame me" post, so why not give him good answers? He wanted to understand something that is not really explained well so I gave him the answer as best I remember it from back when I was first learning DOS basic programing in highschool on a TSR-80(black and white) in 1983.

The dollar sign tells the interpreter that inside the next bracket there's going to be a variable. The parser in turn looks for that variable on the list and returns the value of it to do whatever you want with it.

[aChallenged1]

And that variable is referred to as a "string" because it can be any string of letters and numbers used to define it.

Isn't it an Object.... a string is a type of object, as is an integer and timer. Variables are just /declared objects. But what the hell do I know, I've never even taken a programming class, I'm self taught.

Dictionary.com says:

object
<object-oriented> In object-oriented programming, an
instance of the data structure and behaviour defined by the
object's class. Each object has its own values for the
instance variables of its class and can respond to the
methods defined by its class.

string
<programming> A sequence of data values, usually bytes,
which usually stand for characters (a "character string").
The mapping between values and characters is determined by
the character set which is itself specified implcitly or
explicitly by the environment in which the string is being
interpreted.

Variable
<programming> (Sometimes "var" /veir/ or /var/) A named memory
location in which a program can store intermediate results and
from which it can read it them. Each programming language
has different rules about how variables can be named, typed,
and used. Typically, a value is "assigned" to a variable in
an assignment statement. The value is obtained by
evaluating an expression and then stored in the variable. For
example, the assignment

Yes it's a "string" of values, problem is that in programming lingo a string stands for a sequence of alpha numeric characters. You can't do a mathematical operation on the contents of a sting even if they are numbers without telling the compiler to change it to numerical values first (ASCII Table is a good place to visualize the different between numerical and alphanumerical characters and why they aren't interchangeable) Deep down in a compiler parser what it does is look the address in memory of that variable and it returns it to you.

I love it when people try to explain technical terminology, but their grasp of the meta-language is so poor that matters become even more cloudy.

The things that do stuff to make it such that things of such-and-such a nature do the things that those things do when substituted for those other things are called "pronouns". Learn to use them, please.
