memory, which are unusable
for final storage, may be
created.
Integer
4 kB and
higher
Status
CPUDriveFree
Bytes remaining on the CPU:
drive. This drive resides in
the serial FLASH and is
always present. CRBasicC
programs are normally stored
here.
Integer

(p.
Number of buffers used in all
communication, except with
the external keyboard /
display. Two digits per each
buffer-size category. Least
significant digit specifies the
number of the smallest
buffers. Most significant
digit specifies the number of
the largest buffers. When
TLS is not active, there are 4
categories, "tiny", "little",
"medium", and "large".
When TLS is active, there is
an additional 5th category,
"huge", and there are more
buffers allocated for each
category.
Integer array
TLS Not
Active:
tiny: 05
little: 15
medium: 25
large: 15
huge: 0
TLS Active:
tiny: 160
little: 99
medium: 99
large: 30
huge: 02
