hi,

I've tried numerous ways to remove the 0x0000 from the first 31 entries, I think I should be able to subract it out. Yes, I only think you meant not 31 but first 32 entries. Since I'm using the value of the data entered shouldn't I be able to just subtract 32 from that and then the pointer into the table would just be 0 if the first character was a space, then so on.
Sure, you should do this way. Only some notes: check for input char is above 0x1F surely and do not forget clear C before substraction. Something like: ; ; A - original code CLR C SUBB A,#0x20 JC PRN_CHAR_END ; code is below 0x20 so non-printable ; here process it with your modifyed tables Regards, Oleg |
