Looking at my cf7+ I have over 2000 volumes. I'll never fill all that. But it gave me an idea (forgive me if someone else came up with a similar idea).
What if I could get the TI to look at those extra volumes like sectors of a disk. Maybe set aside, say, volume 500-1000 as one unit with one of the volumes as a File Table for the VHD.
You just do a 'SAVE CFH.FILENAME' and it will save to that area. But, wouldn't you need to create a DSR for that to happen? Is that possible?
I could see where you might be able to create a CALL LINK("savecfh","filename") program that opens up DRV3 to a FAT volume, finds a place in one of the volumes to save your file to then opens that volume in DRV3 and save your file. but not as elegant.
