#115469 - using memory
Hi,

There I'm still learning (who isn't) about programming, i wondered how you can use the memory to use more than 16 stored byte values with the instruction "DB". for so far I'm using this methode where you can call up to 16 memory locations :

Code:    inc      A             ; acc 1x cause of the return
         movc     A,@A+PC       ; get the code out of the table
         ret

;                 capbgefd
Table:   db       00101000b     ; 0    bit-rang  7-6-5-4-3-2-1-0
         db       01101111b     ; 1    segment c-a-p-b-g-e-f-d
         db       10100010b     ; 2
         db       00100110b     ; 3           a
         db       01100101b     ; 4          ===
         db       00110100b     ; 5       f #   # b
         db       00110000b     ; 6          =g=
         db       00101111b     ; 7       e #   # c
         db       00100000b     ; 8          === p   <- decimal
         db       00100100b     ; 9           d          point
         db       01110001b     ; A
         db       01110000b     ; B    
         db       10111000b     ; C    
         db       01100010b     ; D    
         db       10110000b     ; E    
         db       10110001b     ; F


Now i would like to have some system so I can store the whole alfabet and more, if possible. But I think I'll need a whole new methode for that, as here I use the hex-quantety.

Thanks in advance!

John
