The Assembly Language module we will be compiling consists of 3 routines. Just note that Delphi XE2 and above offer alternative options and I will be dealing with those in another article (actually, I already uncovered a bit this matter in the article “ How to use Assembly Language with Delphi 32-bit and 64-bit” but I want to dig deeper). I will be using Delphi 5 to stress how back in time we can go, but it will not make any difference if you use a recent version of Delphi. With MASM the procedure is not guaranteed to work in every case, but usually does. I will use both TASM and MASM to compile the ASM. In this article I will show how to link Delphi with compiled Assembly Language. To see how true this is, just compare the ASM sources for both in the included samples for this article. Those that are used to MASM (Microsoft Macro Assembler) may be surprised to know that TASM is very compatible with MASM, when you are not using the so-called “ideal” mode (and I am one of those that never use the “ideal” mode). Although some people have been spreading around that TASM is dead, that is not really true, it is not updated often but TASM is still the best hassle free 32-bit Assembly Language compiler to work with 32-bit Delphi. You can use MASM to assemble and link in a single step.įor example, to assemble and link ADDIGITS.Some editions of Embarcadero (Borland, Codegear and Inprise as well) products, even some free editions, come with an Assembler called TASM (actually it is TASM32.EXE because we will be using the 32-bit variant, but developers usually refer to it by TASM, the product name). modify your autoexec.bat file's SET PATH line by appending the directory path).

Copy these files into a directory and add it to your search path (i.e. You need these three files ( ml.exe, ml.err, and link.exe) to run the assembly programs. You can get this from (275 KB)Įxecute lnk563.exe to extract link.exe file. Use the linker version 5.60 to generate 16-bit DOS applications. The MASM files ( ml.exe and ml.err) are in the masm32/bin directory.ĭo NOT use the linker link.exe (32 bit) in the masm32/bin directory. To get MASM 6.14, download masm32V8.zip from: (2.98 MB) Microsoft's MASM 6.14 is included in the masm32 package.
