Today I installed DOSBox on Ubuntu in order to learn some Assembly and prepare for the oncoming exams.
sudo apt-get install dosbox dosbox
First I needed to mount a drive using as location an already existing directory. So I made a directory called “dosprogs” in home folder and then ran in DOSBox environment:
mount D ~/dosprogs D:
Files needed for compiling and debugging: debug.exe, tasm.exe, tlink.exe. I found those on the Internet and uploaded them here.
To automate this process even more so I don’t have to do it every time DOSBox runs, I changed the configuration file from ~/.dosbox by adding the following lines at the end of it:
mount D ~/dosprogs D: SET PATH=Z:\;D:\
To make my Assembly programming more pleasant I created a Batch script that runs the assembler, linker and executable file for me:
D:\TASM\tasm %1 if ERRORLEVEL 1 exit \B D:\TASM\tlink %1 if ERRORLEVEL 1 exit \B %1
Unfortunately the “exit” command will also close DOSBox even if I add ‘\b’ afterwards. I don’t know yet how to stop the execution of the script in case of error without also closing DOSBox so the script will actually look like:
D:\TASM\tasm %1 if ERRORLEVEL 1 echo Error D:\TASM\tlink %1 if ERRORLEVEL 1 echo Error %1
[UPDATE] Found the solution:
D:\TASM\tasm %1 if ERRORLEVEL 1 goto end D:\TASM\tlink %1 if ERRORLEVEL 1 goto end %1 :end
The last line I wrote in the DOSBox configuration file makes it possible to run this script from anywhere using:
The file should be sent without its extension (helloW.asm => make helloW).
