Convert an old Basic program to R or Python

We have an old program that was used to calculate biostatistical information for a certain point, but it ran on MS-DOS and it works worse with every new version of Windows that appears. Is it possible to "translate" it to a newer language like R or, if there are good reasons, Python? I attach the code on a pdf file, and also both the whole folder with the code files and the executable file. Please note that I selected the budget for as it is a Micro Project, as it consists on the conversion of about 400 lines of a code that it is already working; but, if reasons are explained, I have no problem about changing the category to the one that it is a fair price for the work. I am at your disposition if more details are needed. Thanks for your attention, Jordi
