%-20.20s
%-20.20s means if the string is LESS THAN 20 bytes, add spaces until it is
equal to 20 bytes...the .20 portion means if the string is GREATER THAN 20
bytes, chop the remaining portion of the string....therefore, you will have
no more than 20 characters on the line, as well as no less than 20
characters.
If you wanted to align the hp and str as you noted, use the following:
sprintf(buf, "Str: %-2d Hp: %3d/%-3d\r\n"
"Dex: %-2d Mana: %3d/%-3d\r\n",
GET_STR(ch), GET_HIT(ch), GET_MAX_HIT(ch),
GET_DEX(ch), GET_MANA(ch), GET_MAX_MANA(ch));
Hope this helps!

the -20 means to align to the left a minimum of 20 spaces. The .20 means it
is a maximum of
