Beta DOS is a great enhancement of the original G+DOS, especially the implementation of random access data files, what G+DOS lacks.
This disk includes a program that fixes all known Beta DOS bugs, and a copy of a fixed system file. But it's better to create our own system file using the original unfixed Beta DOS 1.3:

It will modify our G+DOS system file to create the new "+sys Beta" file. Then we can fix it.
This fixer program was published in May 1996 in the Format magazine (issue 9-9):

The Beta DOS manual is needed in order to learn the new commands:
