sprintf(buffer,"dama= %2.2f rotobat=%d",dama,rotobat)
The prototypes for these functions are placed in the file ctype.h, located in the .\INC subdirectory. This file must be #include -d before using the functions. unsigned char isalnum(char c) returns 1 if c is alphanumeric. unsigned char isalpha(char c) returns 1 if c is alphabetic. unsigned char isascii(char c) returns 1 if c is an ASCII character (0..127). unsigned char iscntrl(char c) returns 1 if c is a control character (0..31 or 127). unsigned char isdigit(char c) returns 1 if c is a decimal digit. unsigned char islower(char c) returns 1 if c is a lower case alphabetic character. unsigned char isprint(char c) returns 1 if c is a printable character (32..127). unsigned char ispunct(char c) returns 1 if c is a punctuation character (all but control and alphanumeric). unsigned char isspace(char c) returns 1 c is a white-space character (space, CR, HT). unsigned char isupper(char c) returns 1 if c is an upper-case alphabetic character. unsigned char isxdigit(char c) returns 1 if c is a hexadecimal digit. char toascii(char c) returns the ASCII equivalent of character c. unsigned char toint(char c) interprets c as a hexadecimal digit and returns an unsigned char from 0 to 15. char tolower(char c) returns the lower case of c if c is an upper case character, else c. char toupper(char c) returns the upper case of c if c is a lower case character, else c.

signed char strcmp(char *str1, char *str2) compares the string str1 with the string str2. Returns <0, 0, >0 according to str1<str2, str1=str2, str1>str2.
