205,Satellite,386 Pentium Laptop.

My binUtils: GNU Assembler Version 2.9.4 <i386-mingw32> using BFD version
2.9.4.Only this displayed after entering in the command line on my laptop:

Syntax: as  -v

How to solve the below Assembly routine?

Please help me to solve this problem.

The below routine I have tried in GAS.  I don’t know the correct syntax for
the below error indicated 4, 5 lines.

       pushl  %ebp                  # no error

       movl   %ebp,%esp             # no error

       movb   %ah,0                 # no error

       les    %bx,dword ptr[%bp+6]  # error



 Error in Line 4: Ignoring junk ‘ptr [%bp+6]’ after expression

  Error in Line 4: Suffix or Operands invalid for ‘les’

       movsd  %al,%es:[%bx]         # error



  Error in Line 5: No such 386 instruction: ‘movsd   %al,%es:[%bx]’

       int    $16                   # no error

       movl   %esp,%ebp             # no error

       pop    %ebp                  # no error

       ret    $04                   # no error

I can’t find any useful info related to my problem (LES,MOVL,DWORD PTR)
from the below . Working examples also not available.

https://sourceware.org/binutils/docs-2.35/
https://sourceware.org/binutils/docs-2.35/as/index.html

Is there any other info required from my end?


 Thanks
