'Jukebox' revisited

Allan Gardner

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.
