Martin Head has been tinkering with a new directory device driver that supports longer filenames (up to 72 characters), by adding a path to the start of any file name provided by the operating system, on a per job basis.
So each job could have a LFN1_ device pointing at a different directory on the same storage medium.
This is just a proof of concept at the time of writing (Martin announced it on 3rd May 2019 on QL Forum)
This is a screen shot from QPC2 showing DIR with and without the added path:
Martin says that he has got QPAC2 to recognise the LFN device.
Anyone wishing to try it out can download the LFN driver and some notes in a PDF file:https://www.qlforum.co.uk/viewtopic.php?f=3&t=2830
