I am pleased that you have got your code working.

Absolutely!
But add those comments - so you remember (and others can easily see) how it works.

However you will need to tidy it up a bit.

True.

It would be easiest to re-write it in C.

False.
The code relies upon timing loops - you do not want to be writing timing loops in 'C'!!

Then you can get your structure correct.

non-sequitur - it is perfectly feasible to write well-structured code in assembler!

Conversely, it is all too common to see poorly structured code in 'C'!

eg, see: http://www.keil.com/forum/docs/thread9632.asp

How To Write the Data to EEPROM (Seial)            01/01/70 00:00      
   Slow the i2c clock            01/01/70 00:00      
      Well i am using 12 MHz with 8051            01/01/70 00:00      
         Speed            01/01/70 00:00      
         this is upon you to determine            01/01/70 00:00      
   the poor developer's "logic analyzer"....            01/01/70 00:00      
   What happens in the real hardware?            01/01/70 00:00      
      writing IS broken - but in several ways            01/01/70 00:00      
         I I Sir, i will use spaces for next, :-)            01/01/70 00:00      
            delay for write plus the real error            01/01/70 00:00      
      Sir i'v used P1 to see that data is written or not            01/01/70 00:00      
         Order of magnitude!            01/01/70 00:00      
         is it 100kHz or 1000kHz?            01/01/70 00:00      
      I dont have osciloscop :-(            01/01/70 00:00      
   In real world the P1 is High,            01/01/70 00:00      
   Code Comments            01/01/70 00:00      
      again "I I SIR", well sir i have got your Point,            01/01/70 00:00      
         to Asif (and others)            01/01/70 00:00      
   I2C Part number ...            01/01/70 00:00      
   Even the NOPs and delay wont working            01/01/70 00:00      
   I have Codded this in C,But still not working :-(            01/01/70 00:00      
      not a good idea            01/01/70 00:00      
      Asif,s C Code for I2C            01/01/70 00:00      
         You missed the point            01/01/70 00:00      
            Point taken            01/01/70 00:00      
   are you sure they are IIC, not SMB            01/01/70 00:00      
      To be very Honest i dont know tha its IIC or SMB            01/01/70 00:00      
         try this            01/01/70 00:00      
   Have you looked here?            01/01/70 00:00      
      Working code...            01/01/70 00:00      
         advice to Asif            01/01/70 00:00      
            i know that i dont have to Copy Paste,, :-)            01/01/70 00:00      
               WoW i have EEPROM Programmer,            01/01/70 00:00      
                  is it working at all?            01/01/70 00:00      
            What about the A0, A1... pins on the 24C04            01/01/70 00:00      
   Well sir Here are Comparision of C and ASM(My Way)            01/01/70 00:00      
      I few I2C questions            01/01/70 00:00      
         it is not uncommon to list IIC addresses this way,            01/01/70 00:00      
            I was askin for schematics...            01/01/70 00:00      
               Here is the Schematics,            01/01/70 00:00      
                  Pardon??            01/01/70 00:00      
                     Well sir it means this ckt is Dummy            01/01/70 00:00      
                        OK            01/01/70 00:00      
                           Well i am straight forward programmer :-)            01/01/70 00:00      
                           Well the Hardware Circuit is Exactly same as it.            01/01/70 00:00      
                              Not at all!            01/01/70 00:00      
                     Recheck it Sir i have added labels, :-)            01/01/70 00:00      
                        but            01/01/70 00:00      
                        and blinkey?            01/01/70 00:00      
                           It really worked :-) MCu is stucked at ACK            01/01/70 00:00      
                              Stuck at ACK            01/01/70 00:00      
                              Stuck in no ACK            01/01/70 00:00      
                                 Sorry i havent understood, forgive my dumbness            01/01/70 00:00      
                                    Stuck in ACK (Reminds me of work)            01/01/70 00:00      
                                    Still Stuck?            01/01/70 00:00      
                                       Sir i am gonna use the Acknowledge polling tech:-)            01/01/70 00:00      
                                          one note            01/01/70 00:00      
                                             Nice note:-) but it Clocking was wrong,            01/01/70 00:00      
                                       Sir i am gonna use the Acknowledge polling tech:-)            01/01/70 00:00      
   Here is working Code, :-)            01/01/70 00:00      
      for your benefit and others            01/01/70 00:00      
         Havent Gotten your Idea ?            01/01/70 00:00      
            The idea is            01/01/70 00:00      
               WoW i have Gotten the IDEA , thanks            01/01/70 00:00      
   The Problem Solved Successfully,Thanks everybody            01/01/70 00:00      
      You have the code working now            01/01/70 00:00      
         Thanks David            01/01/70 00:00      
         Partially agree            01/01/70 00:00

               true and untrue            01/01/70 00:00      
                  C Loops are not Perfect, agreed            01/01/70 00:00      
                  C timing loops            01/01/70 00:00      
                     then don't call it C            01/01/70 00:00
