Hello! I have this code in TASM (from book Wink

) and I want to "translate" this code to FASM, can you help ?

Code:

 
PARA_LIST LABEL BYTE ;This, ...
MAX_LEN DB 20
ACT_LEN DB ?
BN_DATA DB 20 DUP(' ') ;and this.

Haven't used TASM too much, but the last I know. In FASM you put

Code:

times 20 db ' '

OK, I found this on net http://www.clipx.net/ng/masm/ng53eb2.php. LABEL seems to be a stripped-down version of virtual.

See if this work:

Code:

MAX_LEN DB 20
ACT_LEN DB ?
BN_DATA: times 20 DB ' '
virtual at MAX_LEN
  PARA_LIST rb 22
end virtual

Hm..... I write one more time Wink

. I'm going to write program like "hello ..." in FASM, and I want to get text from keyboard (?), and in TASM I'm write (something like psacal's readln() ):

Code:

PARA_LIST LABEL BYTE.
MAX_LEN DB 20
ACT_LEN DB ?
BN_DATA DB 20 DUP(' ') 

mov ah, 0ah
lea dx, PARA_LIST
int 21h

...

And question: How write this in FASM ?

In FASM, names refers to theirs addresses, not its contents like others assemblers.

So, lea dx, PARA_LIST in TASM could be done in FASM:

Code:

lea dx, [PARA_LIST] ; this way

mov dx, PARA_LIST ; or this way

Yeah, this I know Smile

Maybe you can write me simple code ?

Sorry, programming in DOS is desesperating. Sad

But for the snippet you posted, is just follow what I told you.

i'm not sure what you want, but your code would be

Code:

PARA_LIST label byte
MAX_LEN DB 20 
ACT_LEN DB ? 
BN_DATA label byte
times 20 DB ' '

mov ah, 0ah 
lea dx, [PARA_LIST]
int 21h

PARA_LIST label byte
above is just a label/address,
PARA_LIST:
is what I use in Fasm for the same thing.

MAX_LEN DB 20 ;this is the same as Fasm

ACT_LEN DB ? ;this is a reserved byte
ACT_LEN: RB 1
might be the fasm equilivant, but you could just declair a byte
ACT_LEN DB 0

BN_DATA label byte ; another simple label for the assembler to use
times 20 DB ' ' ;this is Fasm
BN_DATA DB "XXXXXXXXXXXXXXXXXXXX" ; replace the X with a space is what I use in Fasm for short declaired arrays.
They are easy to make & view.

mov ah, 0ah ;this is Fasm
lea dx, [PARA_LIST] ; this is just a move address into DX instruction
MOV DX,PARA_LIST ; this is a simple address move also
int 21h ;this is Fasm

Simple is always best (for me anyways)
KISS = Keep It Simple Stupid
is my motto.
