.i64 file The i64 file extension is associated with the Interactive Disassembler, the utility that is used to create assembly language source code from machine-executable code.

idaq打开 .asm file

由于汇编文件只能在x86模式下才能嵌入进C++工程中，而x64下只能采取将asm文件编译成obj文件，然后在链接到工程中，也就是C++调用独立汇编asm文件中的函数

IDC: Constants The following constants can be used in IDC:

• long numbers (32-bit for 32-bit version of IDA and 64-bit for 64-bit version of IDA)

  12345 - decimal constants

  0x444 - hex constants

  01236 - octal constants

  0b110 - binary constants

  'c' - character constants

  Any numeric constant may have 'u' and 'l' suffixes, they are ignored.

• 64-bit numbers. To declare a 64-bit constant, use 'i64' suffix: 123i64

  Also, if a constant does not fit 32-bits, it will automatically be stored as a 64-bit constant.

• strings. Strings are declared using the double quotes. The backslash character can be used to as an escape: "string" "string\nwith four embedded \x0\x00\000\0 zeroes"

  Multiple string constants in a row will be automatically concatenated:

  "this" " is" " one " "string"
