A (Assemble) - direct assembling into memory

Format: A [segment:][address]

     Command "A" activates the mode of direct assembling to the memory.
This begins with the address specified in "segment" and "address"
parameters.  If the address is not specified the program code is placed
either from CS:100 address or from starting address of the loaded program
(if ASSEMBLE command is used for the first time) or from the sector directly
following the last program translated with Asssemble command.  For example,
after entering the command:

        -A 1b4f:7f46

the confirmation is displayed on the screen:

        1B4F:7F46

     If you enter the command without address, the default address will be
displayed.

     After this you may enter the command in standard form.  The Assembler
understands commands by Intel 8088, 8086, 80186, 80286 processors and 8087
and 80287 co-processors. All figures should be entered in hex format.
Indicators should be preceded by size indicators ("word ptr" or simply
"word"), for example:

         -A 100
         1B4F:0100 mov si,word ptr [bp+1]
         1B4F:0103 lds bx,dword [1f46]
         1B4F:0701 mov byte [si+bp+23F],1

     Jump addresses should be preceded by indications of jump type, for
example:

         -A
         1B4F:010A jmp far 567f:6f75
         1B4F:010F jmp short 102
         1B4F:0111 jmp far [si]

     By default, either "near" or "far" is used (in case of double
indicator).  Two pseudo-operators can be used - DB and ORG. DB operator is
transmitting directly to memory the meaning of the following byte while ORG
permits assemblying input commands starting with a random address, for
example:

        -A
        1B4F:0113 org 64f5:00
        64f5:0000 org 100
        64F5:0100 db 1 13 46 ff
        64F5:0104

     You can quit assembling mode by entering an empty line.
