now i’m new to ASM
now i want to run assebler with tasm.exe and tlink.exe
I dont know what different with tasm32,tlink32,masm32?
Can i use them to assembly with my homework
But the first homework that just print «Hello»
I assembler with masm32(that i installed before RadASM) then i got this message:

C:Documents and SettingsHai HoangMy Documentscecs325FIRST.asm(17) : error A2006: undefined symbol : DGROUP
C:Documents and SettingsHai HoangMy Documentscecs325FIRST.asm(27) : warning A4023: with /coff switch, leading underscore required for start address : Hello

On the 2nd try :
i got this message:
Fatal: 16 bit segments not supported in module test1.asm

Any one help me please??

This is for tasm,

hope this helps. If not, tell here.

therock cakmak posted a link for you to click 🙂

i did what u said Cakmak : all 3 step he said
should i edit anything else beside??
I tasm32.exe is fine
but when Link.exe
I got message: Make errors occurs.
Dos screen just go up and flash very quick..but i see somthing message like: «. bad argument..»

Any one can help please??

well the errors are

you use DGROUP somewhere which is probably either a structure or a constant and it has not been defined. You need to define it first so that your assembler knows what it substitutes.

apparantly when making a coff app tasm wants your entry point to be named like _ ? It’s too long since I even looked at tasm, sorry.

I get the impression that you’re mixing 16 bit code with 32 bit code.

May be it would be best if you attached your code to the messageboard so that others can have a look at it? 🙂

Here is the file.asm:

I try run in DOS
I work fine with tasm32 and tlink
but in RAdasm it got message: «Make error occur» after linking

I suggest you create a template for this project and use same project options for everyone. This is because of («) signs which radasm use while supporting long filenames.
put the «dos16.exe» in radasm directory and as in example «.rap» file, replace dos16.exe with tlink.exe in linker option.

dos16.exe only removes the quotes («) from filenames then invokes tlink.exe. Very simple util.

I assume you failed to all 🙂

1. Open the zip archive then get the dos16.exe. And put it in your RadAsm directory(c:radasm).

2. Open RadAsm and then open «Help.rap»(RAdasmProject)

3. For test, do a «Build» or «Ctrl+F5».

. if everything is ok then follow the next steps, else.

4. Open tasm.ini in notepad,
* Find this line,

Type=Win32 App,DOS App

and add replace the two line over originals.

Files=1,1,0,0,0
Folders=0,0,0
MenuMake=0,1,1,1,1,1,0,0

14=0,0,,5
15=
16=*.obj,O,$Btasm32.EXE /zi /I»$I»,*.asm
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
from now on you will have one more option(Dos App) while creating projects 🙂

5. From project menu click on «Create Template». And when a dialog opened, !!important!! click the button, has «. » on it. Choose a file name then OK.

6. When you will create a new project do these,

* File -> New Project and enter project name, description, Choose «Dos App» radio option and dont forget to click on «. » button(this will open list has the name which you named as template) and click the template and go on to wizard(Next->).

Thats All Folks,

note: Dos16 is the program that invokes «TLink.exe» after removing quotes. This was the main problem to solve is it? So, let it rest in RadAsm directory, of course until KetilO(whose writer of this excellent RAD ide) finds a solution for this 🙂

I hope, didnt forget anything 🙂

i did exactly what u said and put «dos16.exe» in directory radasm where radasm.exe and tasm.ini are located
but when i build Help.rap
It did not go through
Tasm is fine, but when linking got message: Make error(s) occurs

So i tried to ignored this, then i create template from it, and create new project what u said..
then i run project. i got message same as above.

If running help.asm with tasm not working at all, is there any way to run it with masm..like:
ml help.asm
But when i run it, i got this message:
C:Documents and SettingsHai HoangMy Documentscecs325help.asm(10) : error A2006: undefined symbol : DGROUP
C:Documents and SettingsHai HoangMy Documentscecs325help.asm(20) : warning A4023: with /coff switch, leading underscore required for start address : Hello

here my tasm.ini : see reply

strange I have got maked the exe without error. The code which you posted here is working good. Did tested with the project which I posted? Where is DGROUP in code?

You can do this job manual as,

Tasm32 Help.asm
Tlink Help.obj

have try this. Which version do you using?

copy and paste here the DOS output, .rap file, your path(autoexec.bat), tasm.cfg, tlink.cfg

I just got error message because i run it with MASM
Now just forget it

I run ok with tasm32 and tlink in DOS window, but i want to use them in RADasm

I want to use TASM
I using verion tasm 5.0

josefalarka How to use 16-bit linker in masm32? I already have the link16.exe file. I have use this command, c:masm32link32 compare.asm Run File [compare.exe] compare List File [nul.map]: compare Libraries [.lib]: compare Definitions File[nul.def]: compare LINK : fatal error L1092: cannot open module-definition file — compare.def Is there any way to modify this code in MASM32 32-bit syntax? Logged

dedndave Member Posts: 12523 ok — first — i dunno where you got link32 — lol this looks like link16 renamed as link32 for the definitions file, just hit enter, as you have no def file Logged

josefalarka Logged

dedndave Member Posts: 12523 well — in the attachment, i sent a batch file named a16.bat place it in the masm32bin folder — you may use it to assemble 16-bit code on the other hand, it is better that you write in 32-bit not sure what your instructor expects he may be disappointed if you write 32-bit code that he doesn’t understand — lol he may also be disappointed if you use the masm32 libraries and macros to accomplish the task Источник Adblock detector

it does assemble using MASM, although both versions have little problems   

both versions use a .END directive, but do not reference the entry point
your version doesn’t initialize the DS register, nor does it terminate properly

as Jochen mentioned, this is 16-bit code and will build if you use a 16-bit linker

i have never used the .STARTUP or .EXIT directives, so i was curious to see exactly what they do
i figured the .STARTUP directive sets the DS register and .EXIT terminates with INT 21h
well, i was half-right   

.EXIT generates the following code, at least when the SMALL model is specified

        mov     ah,4Ch
        int     21hit may generate something different if the TINY model is specified

the code generated by .STARTUP was a little more surprising
again, this is for a SMALL model program and it undoubtedly generates something different for other models

        mov     ax,@data
        mov     ds,ax

the first 2 lines are pretty simple
they load the data segment into AX, then into DS — very common code for 16-bit EXE’s

the rest of the code forces the SS register to reference the same segment as the DS register
a bit of a mystery for a beginner, probably
but it’s forcing the .DATA segment and .STACK segment into a single GROUP
not really sure why they do that — it isn’t necessary, in many cases

personally, i would write the program to look something like this…

;###############################################################################################

i would also add a couple other directives, but that’s beyond what the teacher wants
you could replace the first 2 lines of code with .STARTUP and the last 2 with .EXIT, just to make him happy   

_main   PROC

the program doesn’t appear to do much when you run it
but, it does return an exit code of 8 (5+X), that could be accessed in a batch file with ERRORLEVEL commands
