It was originally set up with BASIC version 4, and we just upgraded to BASIC 5.13. The manuals for the new BASIC haven't arrived yet. [I realize that this is not a Precision Architecture machine running Unix and X-Windows, but it does the job it was bought for]. Recently we started running out of space on the hard disk (no kidding, with only 10 Meg, but it gets worse). When we added up the files, they only came to about 1.5 Megabytes! Some poking around with the BASIC utilities seems to indicate that the hard disk has been partitioned (by the previous user) to four volumes of about 2 Meg each (actually about 9800 records of 256 bytes). I tried using INITIALIZE again, but this only formats one partition at a time. So, my question is: How do you un-partition the hard disk, and get it back to being just one volume? I did call the local HP office, and they said everyone who knew this sort of thing was out of town. While we're on the subject of disks, I see that BASIC 5 now supports a Hierarchical File System. How much overhead does this consume on the disk? And does it eliminate the requirement that files be stored on contiguous blocks?
