Parameter
Q=query

EXAMPLE:
Description
Normally, before disk formatting begins,
the system issues the following prompt:
READY?
Responses other than 'Y' or 'y' abort the
format attempt. This verification may
be
bypassed by specifying 'Q=N'. The default
is IQ=Y'"
This option may be used to override the
default directory size of
5
blocks. The
directory will grow to accomodate more
filenames, but the directory blocks will
no longer be on the same track and seeks

USAGE:
formats the disk in drive

as a system disk with an initial
directory size of 15 blockso
The format program writes sector
0
so that the sector interlace map
which maps logical records to disk addresses is valid. The format
program then downloads a program which writes a known pattern on
all sectors after sector 00 After this program completes, the
following message is written to the console:
WRITE
PASS DONE
The format program then downloads another program which will read
back all sectors and build a free chain from which to allocate
blocks to files. After this program completes, the following
message is written to the console:
VERIFY
PASS DONE
On a
5
megabyte platter, this will occur within approximately
5
minuteso If any blocks were read with an error, their record
