You could use the strncat() function to append one character
to the 'Dato' string. Example:

The program below has the following output:
Quote:
ABC342

Code:

#include <16F877.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

#include <string.h>

//======================================
void main()
{
char Dato[20] = {"ABC"};
char Entrada[10];

Entrada[0] = '0';
Entrada[1] = '1';
Entrada[2] = '2';
Entrada[3] = '3';
Entrada[4] = '4';


strncat(Dato, &Entrada[3], 1);
strncat(Dato, &Entrada[4], 1);
strncat(Dato, &Entrada[2], 1);

printf(Dato);


while(1);
}

Use the get_float() function. It will receive a string and convert it to
a floating point value. Example:

Run the program below. Then type in a floating point number, such as
123.45 and then press the Enter key. The program will display the
number that it received. It will be stored in the 'value' variable.
Quote:
123.45 value = 123.45
777.56 value = 777.56

Code:

#include <16F877.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

#include <stdlib.h>
#include <input.c>

//======================================
void main()
{
float value;


while(1)
  {
   value = get_float();
 
   printf(" value = %7.2f \n\r", value);
  }

}

Where do the input strings come from ? Do they come from a GPS ?

You answered yes in a PM, so you need find some sample code written
in CCS, that will parse a NMEA-0183 GPS stream.

Here is one:

Look at the nema.c file.
