moving message with 16f628

[fer38]

hi everyone,

i have just joined this forum and ı think i am on basic level in pic programming. I am using a 16f628 and 2x 74ls154 to drive 16 column of a 8x8 display to make a moving text.

up to 16 character that ı enter in lookup command moves rıght to left as i intended well,for example "HI EVERYBODY" .
However if ı exceed the 16 barier(limit) message is distorded.
here my question :
how could ı write a message in lookup command more than 16 characters and then move it correctly?
note:
my characters in eeprom and the matrix register that i used is size of[80]

thank you so much indeed for now...

i have tried to divide a long sting message,let say composed of 300 char, to small parts each one consists of 64 char. at first sight it seemed to be ok. however when the message reaches the 4th part of the whole length i observe a distortion again.ı would like to make a moving message that can move 1000 char , how could i solve this problem?

i am waiting for your answers
thanks,
