There have been a number of enquiries lately about my
Jukebox program which was published in AMPLINEX 017. There have also been some
kind comments for which I am grateful.
Firstly, I would like to answer the question about making
the program suitable for ADFS. Whilst it would be perfectly feasible to modify
the program, there are a number of problems associated with the change. The
major one is that I have insufficient knowledge of the ADFS to perform the
changes myself and I do not have access to an ADFS machine to develop the code
in this direction. However if anyone has the know-how, inclination and machine
to do the work I will be very willing to assist if he/she would care to contact
me through AMPLINEX.
Next, an enquiry was made about changing the program to work
with a 62-file DFS. This is a little simpler to implement. Although Matthew
Grist (Question and Answers AMPLINEX 019) did not specify which particular DFS he
was using, I have made the necessary modifications to work with Watford
Electronics DFS (1.44) 62-file catalogues and have included the necessary
modifications in the form of a file which should be EXECed into the Jukebox
program as published in AMPLINEX 017.
The obvious change to the way in which the program is used
is that only one side of a disc can be catalogued at one time, (a mode 7 screen
would not be able to show 124 files in any sensible way). The 'd' key which selects
the drive to be catalogued, now steps through the available 'sides' of drives
in an order determined by the word 'setdrv'. This word should be edited (e.g.
in Notepad) to suit the setup required. Commenting out any unwanted lines with '%'
is probably the best way to change 'setdrv'.
Don't forget to save the modified program back to disc (the
'save' command is built into the program for this purpose).
Please let me know if it works the way you want it to.
