CCS 'C' comes with a whole load of standard string handling functions.
Have a look there, you should find what you want.

I did look string handling, and found different way to get same results...but Iwould like to hear about experts what is best...mean more effective.
memmove(x,x+2,5); worked ...but I´m not sure if is the right one |

Post the final string that you would like to see. Do you want "12345" ?
Then you can use this function:
atoi32(char *ptr)
The atoi32() function takes a pointer to the string as its parameter.
Just point it to the 2nd char in the string. Example:
| Code: |
#include <18F46K22.h>
#fuses INTRC_IO,NOWDT,PUT,BROWNOUT
#use delay(clock=4M)
#use rs232(baud=9600, UART1, ERRORS)
#include <stdlib.h>
#include <input.c>
//===========================
void main()
{
int8 input_array[20];
int32 result;
get_string(input_array, 10); // Get 10 chars max
result = atoi32(input_array +2);
printf("result = %lu \n\r", result);
while(TRUE);
}
