[net.micro.cpm] Bubble memory - CP/M directory - HELP!

	Does anyone in netland know how CP/M structures its
directorys? I am trying to interface an Intel bubble memory
to a Systems group S-100 processor and am having trouble 
with the directory. I can use ddt to load a program into
RAM, escape from ddt and SAVE the file in the bubble memory
without any problem. The file appears in the directory for
the bubble pack, yet I cannot PIP to the bubble without
getting an error - NO FILE - from PIP. Envoking ED from the
bubbles causes the error message DIRECTORY FULL to be returned.
	I am following the guidelines set out by Louis Wheeler
in his Byte articles, but he makes no mention of this type of
problem. I would appreciate mail from anyone who has an idea
as to how I may overcome this difficulty.

Stephen,

I could recommend the older book "Programmer's Guide to CP/M", extracted
articles from older Microsystems Magazine, Microsystems Press.  It has many
details on the CP/M library schemata.

Try to get a copy of DU (Disk Utility). This famous public domain
software will not only show you how the directory is organized, but will
also let you modify it.
