RE: 1581 Disk Partitions

Hi Pasi,

I experiemented also a little bit last night and added some of the partition
selection commands to the next version of 64HDD.

>> 3) are files stored only in the partition space allocated between "start"

This is very helpful information for when I complete the partion 
creation" functions next week. Just to check that I have it correctly...

When the new partition is created the BAM in the parent is allocated all the
blocks the partition has been assigned. However, after a N: is given the
partition BAM has all blocks outside the partition (and local dir-track)
allocated, and the free space in the partition "free" and that is how DOS
knows how to allocate within the partion space.

Many thanks,
