Good evening

Meanwhile I remembered something... and it works!

char Debug[40];
char* cstr(int Parametro){
itoa(Parametro,Debug,10);
return strdup(Debug);
}

char *concatena(char *string1, char *string2) {
strcpy(StringFinal, string1);
strcat (StringFinal, string2);
return StringFinal;
}

DD=atoi(concatena(cstr(Dia1),cstr(Dia2)));

Thanks
Best regards

How about remembering some math from school and doing the following?

DD = Dia1 * 10 + Dia2;

Doing it with strings is a little like going from London to Paris via New York and Singapore.

Thanks Korman

That's why I've putted the code here.
I'm always expecting that somebody knows a better way to do it.

Thanks once again

If those Dia1 and Dia2 are comming from the serial port save then using chars and only use an int when joining then, as that will save you some ram.
