Sorry, I assumed you were using an 18F, which can have problems with EEPROM Math.
Since you are using a 16F628, please ignore my previous comment.

Not sure why you would get that error with a 16F, so give this a try and let me know what happens.
Set you're OSC and LCD defines first ...

sory Darrel,

the one i do id for the LED matrix display. the data include happy face. letters....scrolling. for the alphabets i store in one data file , the happy face i do it in another data file.

i.e. running_letter DATA $10,$10...$30..
running_face DATA $30, $68....
the label give out the error when compiled
------------------------

for i = 0 to 3
READ running_letter +i, temp ; tenp is temporary storage

next i
--------------------

the pic is 16f628
i could not find rhe ERRORLEVEL in the data sheet of that chip

thank for your attention

regards,
