VPAR has the following form:
{ x
left
, x
right
, y

For plot type WIREFRAME, the elements of VPAR are used as follows:
• x
left
and x
right
are real numbers that specify the width of the view space.
• y
near
and y
far
are real numbers that specify the depth of the view space.
• z
low
and z
high
are real numbers that specify the height of the view space.
• x
min
and x
max
are not used.
• y
min
and y
max
are not used.
• x
eye
, y
eye
, and z
eye
are real numbers that specify the point in space from which the graph is
viewed.
• x
step
and y
step
are real numbers that set the number of x-coordinates versus the number of y-
coordinates plotted.
The plotting parameters are specified in the reserved variable PPAR, which has this form:
{ (x
min
, y
min
) (x
max
, y
max
) indep res axes ptype depend }
For plot type WIREFRAME, the elements of PPAR are used as follows:
• (x
min
, y
min
) is not used.
• (x
max
, y
max
) is not used.
• indep is a name specifying the independent variable. The default value of indep is X.
• res is not used.
• axes is not used.
• ptype is a name specifying the plot type. Executing the command WIREFRAME places the
command name WIREFRAME in ptype.
• depend is a name specifying the dependent variable. The default value is Y.

WSLOG
Type: Command
Description: Warmstart Log Command: Returns four strings recording the date, time, and cause of the four
most recent warmstart events.
Each string "log
n
" has the form "code–date time". The following table summarizes the legal values of
code and their meanings.
Code Description
0 The warmstart log was cleared.
1 The interrupt system detected a very low battery condition at the battery contacts
(not the same as a low system voltage), and put the calculator in “Deep Sleep
mode” (with the system clock running). When $ is pressed after the battery voltage
is restored, the system warmstarts and puts a 1 in the log.
2 Hardware failed during transmission (timeout).
3 Run through address 0.
4 System time is corrupt
