Hope this makes sense now

- Absolutely yes. Thanks, Michael, for the lesson. And Raghu for the another idea.

For Jeremy:
From look-up Michael provided it is easy to convert to ascii decimal (only adding 30h to nibbles). The way you offer seems to be more complicated for converting to digits in ascii, if i understand eveything right (especially when writing code in assembly).

But the last point should be put for this subject. As my program will run in ext. memory (i'm repeating), as i understand i will have no code memory (8051 rom is used only for loading my *.asm in RAM. Then EA will be switched for running program only from RAM).
So i still may use DB or DW directives (for reserving bytes or words in code memory) in my code which will be loaded in ram???
Does nothing changes? I should write the *.asm code as i would write it for placing in internal ROM?

Please, dont ask me about this freaky usage of ram.

I apologize for the incomprehension once again,
Rob
