I'm writing a simple scripting program (so far, it can 'print'), but can't think of a good way to store variables that the user creates in the script. does anybody have any idead? thx.

... binary ... tree??
can u elaborate on that thought, plz?
Hmmm, a linked list might be a better to start off with (search the board, been covered alot).
Each node in the list may contain the variable name and its current value.

OK! Link-lists are in my book.... that may be a little hard to implement... but I can see how it can be done. thx. (though, arrays might be a problem in the future...)

Actually, a hash table would be better suited for this purpose, and it has the advantage of being simpler to understand than a linked list or binary tree for a newcomer.

Check the General Discussion board. I posted an extensive (if incomplete at the time) tutorial on binary search trees under the thread "Request for Comment".
My best code is written with the delete key.
got it to work.
I have 2 BIG arrays (1000 elements), and keep the name of the variable in 1, and the value in the other. I also have an int that holds the value of the next empty element.
I only have char, though.
any thoughts on how to read text and convert it to an interger?

When all else fails, read the instructions.

OK. I found a way. Phobos (a D lib) has a toInt function.
If you want to learn to write portable code, use a standard conversion function as mentioned in the FAQ. Your choice...

then what's the prototype for atoi()?
EDIT
nevermind. it doesn't work (in D).
but I still found the prototype:
int atoi(const char *nptr);

P.S. D IS portable! there is a Win32 and Linux version.
the last time the test script uses this I get an error. it's always the last one, no matter what I tell it to put.Code:void _putchar() { int i = 0; int ii = 0; char var_name[32]; while(buff[i] != ' ') { i++; } i++; for(ii = 0; buff[i] != ' ' && buff[i] != '\n' && ii < var_name.size;i++,ii++) { var_name[ii] = buff[i]; } for(i = 0;var_name[0 .. 32] != c_name[i][0 .. 32] && i < 1000;) { i++; } if(var_name[0 .. 32] == c_name[i][0 .. 32]) { putchar(c_value[i]); } if(_bdebug) { printf("\nvar_name: %.*s\nc_name: %.*s\ni: %i",var_name,c_name[i],i); } nullify(var_name); return; }
the error I get is: "Error: Access Violation"
