•
(x
max
, y
max
) is a complex number specifying the upper right corner of PICT (the upper right
corner of the display range). The default value is (6.5,3.2) for the HP 48gII and (6.5,4.0) for the
HP 50g and 49g+.
•
indep is a list containing a name that specifies the independent variable, and two numbers
specifying the minimum and maximum values for the independent variable (the plotting range).
Note that the default value is X. If X is not modified and included in a list with a plotting
range, the values in (x
min
, y
min
) and (x
max
, y
max
) are used as the plotting range, which generally
leads to meaningless results.
•
res is a real number specifying the interval, in user-unit coordinates, between values of the
independent variable. The default value is 0, which specifies an interval equal to 1/130 of the
difference between the maximum and minimum values in indep (the plotting range).
•
axes is a list containing one or more of the following, in the order listed: a complex number
specifying the user-unit coordinates of the plot origin, a list specifying the tick-mark annotation,
and two strings specifying labels for the horizontal and vertical axes. The default value is (0,0).
•
ptype is a command name specifying the plot type. Executing the command PARAMETRIC
places the name PARAMETRIC in PPAR.
•
depend is a name specifying a label for the vertical axis. The default value is Y.
The contents of EQ must be an expression or program; it cannot be an equation. It is evaluated
for each value of the independent variable. The results, which must be complex numbers, give the
coordinates of the points to be plotted. Lines are drawn between plotted points unless flag –31 is
set.

PARITY
Type: Command
Description: Parity Command: Sets the parity value in the reserved variable IOPAR.
Legal values are shown below. A negative value means the calculator does not check parity on
bytes received during Kermit transfers or with SRECV. Parity is still used during data
transmission, however.
n-Value Meaning
0 no parity (the default value)
1 odd parity
2 even parity
3 mark
4 space
For more information, refer to the reserved variable IOPAR in appendix D, “Reserved
