ARCHIVE

Type: Command
Description: Archive HOME Command: Creates a backup copy of the HOME directory (that is, all variables),
the user-key assignments, and the alarm catalog in the specified backup object (:n
RAM or flash ROM.
The specified port number can be 0 through 3, where 3 is the SD card. (This only applies to the
hp49g+.) An error will result if there is not enough memory in the specified port to copy the
HOME directory.
If the backup object is ":IO: name", then the copied directory is transmitted in binary via Kermit
protocol through the current I/O port to the specified filename.
To save flag settings, execute RCLF and store the resulting list in a variable.

ARG

Type: Function
Description: Argument Function: Returns the (real) polar angle of a complex number (x, y).
The polar angle is equal to:
• atan y/x for x
• atan y/x +
• atan y/x + 180 sign y for x < 0, Degrees mode
• atan y/x + 200 sign y for x < 0, Grads mode
A real argument x is treated as the complex argument (x,0).
