XRECV

Command

 

 

Type:

 

 

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:

…µXRECV

 

 

Flags:

XRNG

Command

 

 

Type:

 

 

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 xmin and xmax in the complex

 

numbers (xmin, ymin) and (xmax, ymax). 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 xmin and xmax are –6.5 and 6.5, respectively.

XROOT

Analytic function

 

 

Type:

 

 

Description:

xth Root of y Command: Computes the xth root of a real number.

 

XROOT is equivalent to y1/x, but with greater accuracy.

 

If y < 0, x must be an integer.
