     What font did you try?

     Here a user said that Tahoma worked for him: https://forum.tuts4you.com/topic/21128-multiline-ultimate-assembler/page/3/#comment-103871

   Any chance to change this to asmjit in x64dbg? It seems to be using XEDParse which has issues.

   I can’t get it to assemble “movss dword ptr ss:[rsp+0x18], xmm2”

     Multiline Ultimate Assembler uses the debugger’s API for assembling instructions. For x64dbg, I believe that the last engine you used as a single command assembler is then used for the API. Try focusing on a command and pressing space, then select an engine and use it.

   Any idea how to add float ? or add it as hex directly?

   @float 2.5

   Or

   BINARY dc cc cc 3c

   Is there a syntax guide i can learn from?

     Any idea how to add float ?

     You can use data instruction commands, for example real4 2.5. See the relevant PR for details.

     or add it as hex directly?

     You can use data instruction commands for that, too. For example, bytes:

     db 12
     db 34
     db 56
     db 78
     

     Or a double word right away: dd 12345678

     You can also use the plugin’s string syntax, for example: "\x12\x34\x56\x78".

   what about integers? When i do this

   int 10

   debugger shows
   CD 10 00 00

   where it is supposed to show:
   0A 00 00 00

     int 10 is a software interrupt assembly command. Try dword 10. You can refer to the pull request I linked earlier.

       I do tried dword 10 but it produces the same result
       10 00 00 00 and not integer 0A 00 00 00.

       I looked through the pull request but did not find any relatable format the same way that is possible to say for floats ( real4 2.5 for example)

         0A 00 00 00 is much closer than CD 10 00 00 🙂 try using 0x10 instead of 10 for a hex value.

             ok my bad i misread your comment, i think you misread mine or I did not explain correctly.

             dword 10 produces 10 00 00 00

             dword 0x10 produces 10 00 00 00

             I am looking for 0A 00 00 00

             i want input to be INT and output HEX

               Sorry, it was a quick reply from my phone. I’m not sure that’s possible. Multiline Ultimate Assembler has some syntax that it understands, such as labels and address blocks, and the rest is forwarded to x64dbg. So it’s more of a question to x64dbg. They have a Discord channel, you might want to ask there.
