Fix the warnings, they're there for a reason.

There is an array of the race names somewhere, if you used Nashak's
snippet then it is pc_race_types.  You can easily get the name for
printing just by doing pc_race_types[race] where race is the variable
with the number of the race.

Post the relevent code so we can see exactly what is happening.

That problem comes from appending to the existing buffer rather than
overwriting it.  You are doing something like this...

sprintf(buf + strlen(buf), "Name: %s\r\n", name);
sprintf(buf + strlen(buf), "Age: %s\r\n", age);
sprintf(buf + strlen(buf), "Level: %s\r\n", level);
sprintf(buf + strlen(buf), "Score: %s\r\n", score);
send_to_char(buf, ch);

What you really need to do is overwrite the buffer for the first entry
and append for the balance as follows...

sprintf(buf, "Name: %s\r\n", name);
sprintf(buf + strlen(buf), "Age: %s\r\n", age);
sprintf(buf + strlen(buf), "Level: %s\r\n", level);
sprintf(buf + strlen(buf), "Score: %s\r\n", score);
send_to_char(buf, ch);

You might also see strcpy or strcat lines which do the same thing as
sprintf but for writing unformatted strings.  strcpy should be used for
the first line as it overwrites the buffer and strcat should be used for
the rest of the lines as it appends to the buffer.

>   The offending line is:   send_to_char(buf, ch)

All this line does is send the contents of buf to the player's screen
it's fine and is NOT the offending line.

Chances are that you took out the first line of the original score
command that overwrote the buffer instead of appending to it, after that
you can take out as many lines as you want and it will still have that
problem.  The problem is with the line you took out, you need to change
the next line to overwrite instead of append.

Yes, but you shouldn't have to use it...

*buf = 0;
