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: …»

XSEND
Type: Command
Description: XModem Send Command: Sends a copy of the named object via XModem.
A receiving hp49g+/hp48gII must execute XRECV to receive an object via XModem.
The transfer occurs more quickly if you start the receiving XModem after executing XSEND.
Also, configuring the receiving modem not to do CRC checksums (if possible) will avoid a 30 to
60-second delay when starting the transfer.
If you are transferring data between two hp49g+/hp48gIIs, executing {AAA BBB CCC}
XSEND sends AAA, BBB, and CCC. You also need to use a list on the receiving end ( {AAA
BBB CCC} XRECV, for example).
