Greetings,
I installed DOSBox because because I have many old compiled programs (*.exe) from various versions of FORTRAN that I have written/accumulated over the years, and I want to run them on newer machines.

The DOSBox installation went smoothly, but when I run a program, only the first line of the program executes. I have many programs where data are entered interactively (user is prompted for input); however, I only get the very first prompt. What gives?

Any assistance would be greatly appreciated.

Thanks, John

DOSBox is not intended for running old FOTRAN programs. My first suggestion would be to see if it works in vDosPlus, especially as it is using a more recent version of the code than the official 0.74; if it still doesn't work, they might even be interested in making appropriate changes, if it's not a major problem.

Otherwise, there are many possibilities here. You might need to change the "machine" type in DOSBox.conf, or the program might require features from real MS-DOS (in which case using the 4DOS shell might help), or possibly low-level disk access (in which case you could try putting your programs on a bootable floppy image and then booting the floppy in DOSBox).

Or you can just dispense with DOSBox entirely and use a proper virtual machine like VMware Player.

Thanks for your timely responses...I will look into your suggestions. Fortunately, I still own several ancient laptops that can run my programs but you never know how long they'll last.
