XRECV
Type: Command
Description: XModem Receive Command: Prepares the calculator to receive an object via XModem. The
received object is stored in the given variable name.
The transfer will start more quickly if you start the XModem sender before executing XRECV.
Invalid object names cause an error. If flag –36 is clear, object names that are already in use also
cause an error.
If you are transferring data between two calculators, executing {AAA BBB CCC} XRECV
receives AAA, BBB, and CCC. You also need to use a list on the sending end ( {AAA BBB
CCC} XSEND , for example).
Access: …µ XRECV
Flags: I/O Device (–33), RECV Overwrite (–36), I/O Device for Wire (–78)

XRNG
Type: Command
Description: x-Axis Display Range Command: Specifies the x-axis display range.
The x-axis display range is stored in the reserved variable PPAR as x
min
and x
max
in the complex
numbers (x
min
, y
min
) and (x
max
, y
max
). These complex numbers are the first two elements of PPAR
and specify the coordinates of the lower left and upper right corners of the display ranges.
The default values of x
min
and x
max
are –6.5 and 6.5, respectively.

XROOT
Type: Analytic function
Description: xth Root of y Command: Computes the xth root of a real number.
XROOT is equivalent to y
1/x
, but with greater accuracy.
If y < 0, x must be an integer.
Access: …» (» is the right-shift of the Rkey).
Flags: Numerical Results (–3)
