I dont know if there is something implemented like this but I always run into the same tedious task. I want a RunOnce function or object type implemented into the language. I know i could write my own but this is something im sure is common with every program. If you want something to only run once but you put it in a section of code that gets read over and over, Exactly like static but for function calls. HMM maybe you can use static that way. I end up using a static bool value = false.. and then when i want to run the object once I do this: if(value == false) { foo(); // this is the function i only want to call once value = true; } There has to be a better way to do this. I dont know the best way to fix it but im sure someone out there has an idea. Its so common especially in game development for me when I am playing sounds. I think it should be implemented into a language . Maybe it is in some language already i dont know. What do you guys think? [edited by - goomyman on June 3, 2002 12:01:03 AM]

while(1)
{
static int bob=runonce();
/* ... */
}

Well, if a new language was created that had this feature perhaps the syntax would be something like this:

static
{
...
}

This would cause the code to be executed once, or if you wanted it to be executed a limited number of times (but more than once), you could do something like this:

static (n)
{
...
}

Where n is the number of times to execute (though in this case perhaps a new keyword should be invented?).

Another thing I think languages should have is the ability to return more than one value from a function. Note: Passing in variables using pointers ISN'T the same as returning multiple values (although it has the same effect). The syntax would be:

(int, int, char) my_func(...)
{
int a, b;
char c;
...
return (a, b, c);
}

int main(void)
{
(int a, int b, char c) = my_func();
(int d,,) = my_func();
return 0;
}

Of course if there was only one variable being returned it would look like normal. Does anybody else have ideas for new syntax?

Give a man a fish and you feed him for a day; teach him to use the Net and he won't bother you for weeks.

Lua handles multiple returns. Or was that Python? Maybe both.
