Thanks a lot mam . This are very very helpful before practical examinations.

[thefourhourtalk]

thankyou so much teacher ! youve helped a lot

[MrunalHolmukhe]

Mam bt how to learn mnemonics? Like we have so many problems so how will we get to know that LXI will come first or MVI? Pls reply ....

[NarutoUzumaki-nkkp]

Is there a need for flag register to be drawn in the exam after the program?

[ojaspatil]

maam do we need to show the code compilation in board exam?

[shravanitembare]

Mam, I wrote the above program using the following instruction:

LXI H, 2030 H
MOV A, M
INX H
ADC M
INX H
MOV M, A
RST 1
(Our teacher told to use RST 1 in Practicals and HALT in Theory exam.)

Is it correct?

[akashgangurde]

Trasing of programm kya hota hai mam .

[rashmijain]

Mam why do we need to mention the LXI code ..why can't we directly start with MOV code.?

[anaykhanolkar]

Hello Ma'am, in compilation we only have to write the mnemonics and not the end result of the step; right?

[sanas]

Ma’am I have tried to do this program by myself, but I have used different instructions. I then complied it to check and got what was asked. So can you please tell if i will get marks if I write the program as following?

LXI H, 2030H
LDA 2301H
ADD M
STA 2030H
HLT

Only the space in memory has increased (i.e. 11 bytes). So will this program be correct according to board?

[Ankit]

Mam can you please tell me that from where the 07 and 06 came in compilation😢😢

[tanishrane]

Exam me sirf code likhe ki compile bi kre (number solving)?

[rittikarijhwani]

ma'am hex code ka column nahi aayega?
