Strings

i'm having trouble adding characters variable string.  the examples didn't me much.  it shows how declare them not how manipulate them.

i have keypad working fine , displaying random alphanumberic code on lcd screen. want save string.  i believe have refer each character in string when mod cant work.

sample code plz.

i use excellent library when there might more efficient way because seems intuitive me:

since derives print, can create strings in buffer printing led.

it may overkill, it.
