re-compile IDA pro disassemble code[HELP Please]

[TSecurity]

hiii...

I disassemble the .exe file via IDA pro 6.1 and necessary for me to mutation the IDA pro asm code and re-compile it.
But, disassembled code of exe file produced via IDA pro, don't re-compile with masm or other assemblers without I had been applying any mutation.
why disassembled code of exe file produced via IDA pro don't re-compile?

sorry for incorrect verb use and grammer in my txt.

Probably because IDA Pro doesn't bother to reproduce the syntax of any particular assembler.

You will have to read the documentation of whatever assembler you are using, and find out what its wants are.
