•(xmax, ymax) 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 (xmin, ymin) and (xmax, ymax) 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
