How can i check the 8051 assembly code in keil software?
is there any other IDE for that? if yes please send me a link.
Yes, it is considered SHOUTING to use capital letters.
The IDE does support assembler files, and will know that they should be assembled before linking, instead of compiled.
But your original post didn't sound like you wanted to know how to build projects containing assembler files. It sounded like you wanted to see the disassembly - the instructions generated by the compiler. At least the commercial edition of the compiler can produce list files with assembler output. I don't think the evaluation version supports that.
