::> Hello.  I am new to this area.  I have worked with C++ for almost a year, 
The code you posted was C, not C++. 
::> unsigned char Monster_Name;
::> Monster_Name = "Bear";
You only set up space for 1 char, you need to set up an array (or a pointer 
and allocate space for it).
unsigned char Monster_Name[21];   // Gives you 20 characters + trailing \0
                                  // to work with.
strcpy(Monster_Name, "Bear");
::> printf("%s", Monster_Name);
%s is for a \0 terminated character array, but you passed a single unsigned
char.  With the above changes it should work. 
::> The warning I get is this :
::> Warning Nonportable pointer conversion in function main
Monster name is type unsigned char, "Bear" is a const char pointer 
mplicit).
::> My next question is how do you use dos commands in C++.  I mean if I 
ante
::> make a program that could show all the files in a certain directory, or 
a

look up system() in your help.
::> My last question is this.  How do you save to a seperate file (name of 
er

::> program?                                                                  
In C++, you'd probably use fstream's.
As for you code sample, let's make it C++ and stay on topic:
::> #include                                                         
::> main()                                                                    
::> {                                                                         
::> unsigned char Monster_Name;                                               
::> Monster_Name = "Bear";                                                    
::> clrscr();                                                                 
::> printf("%s", Monster_Name);                                               
::> getch();                                                                  
::> return(0);                                                                
::> }                                                                         
// off top of my head - May contain errors
#include 
#include 
int main(void)
{
   char inkey = 0;
   unsigned char *Monster_Name = new unsigned char[21];
   strcpy(Monster_Name, "Bear");     //pure C++ enthusiasts might recommend
                                     // strstream's instead
   clrscr();                         //non-portable?
   cout << Monster_Name;             //print it
   while (!inkey) cin >> inkey;     //wait for keypress
   delete[] Monster_Name;           //clean up 
   return 0;
}
