add byte(8-bit register) to a word(X,Y,Z-register)
If X is pointing to a specific data in the SRAM (perhaps some kind of table), you can avoid worrying about XH if you ensure that the data in SRAM does not cross a 256-byte...

Difference at 0000 Problem
There is not much help that can be given. As Lee pointed out, its clear that you are not communicating with your chip. You did not specify how your hardware is setup so no...

Entering programming mode... FAILED!
AFAICT, you can still program the part with the SPI interface if debugwire is enabled, but maybe the clock fuses got set wrong. Did you read "Serial High Voltage Programming" in...

security lock bits LOL, is the thievery business really so slow that you must dig up old threads that relate to reading a locked MCU in order to advertise? :roll...

variable passing bug in ASM2 beta5
You can workaround the problem by setting a symbol equal to @0<<1 and passing that symbol to mLevel2 .macro mLevel1 .set mLevel2_arg2 = @0<<1 mLevel2 4,5,...

Which AVR to choose
I'm not sure if Bascom supports ALL of the devices, but surely it supports the ones you mentioned. Download the demo version of Bascom and check it out.

external oscilator STK500
Did you confirm that the fuses are not set for the internal RC oscillator?

Which AVR to choose
Just about any AVR beats the pants off of a Basic Stamp as far as RAM and program memory. When you say that you want more EEPROM, does that translate to wanting more program space...

can SPIEN be cleared when serial programming?
According to the datasheets, SPIEN is not accessible in serial mode. It appears to be so for all the AVR devices, although I thought I remembered seeing a datasheet that said...

default value in flash, what opcode?
Filling the last instruction with 0x0000 (NOP) would work, would it not? If it lands on the last NOP, it will execute it and end up at the reset vector. If the NOP gets skipped...

default value in flash, what opcode?
While the information is from an old datasheet, current devices exhibit the same behavior.
