To ewaluate a tjackyp object:
B Display the appropriate PORT menu, then press the menu key for
the object,
or
B Enter the backup identifier for the backup object and press f EVAL ).
To evaluate several backup objects in a row, enter a list (with C >
delimiters) containing the backup identifiers, then press (EVAL) for each
backup object.
To delete a backup object:
B Enter the backup identifier for the backup object and press
OCEuM). You can’t delete a backup object that you recalled to
the stack—you get the Ob.ject in Use message. If you delete the
object from the stack or store the object in a variable, then you can
delete the backup object.
To purge seweral backup objects simultaneously:
1. Enter a list (with C > delimiters) containing the backup identifiers.
2. Press OCESM)-
To search ail ports for a backup object:
1. Enter the backup identifier for the object—except use & for the port
number. (Press ENTER) to type &.)
2. Execute RCL, EVAL, or PURGE. Whenever you use the is
“wildcard” character for the port number, the HP 48 searches ports
in reverse numerical order beginning with the highest available (32,
31, ... , 2, 1, 0) and then main memory for the backup object—it
uses the first occurrence of the name.
Example: If you enter : its B
e
GI and press 0(PURG], you delete the
first occurrence of BPGl in port 32, 31, ... , 2, 1, 0, or
main memory.
To get a list of backup objects in a port:
Enter the port number and press OCy BRARY) KVflRiB. The
PVARS command actually returns two results. Level 1 indicates the
type of memory contained in the port; "ROM” (application card),
"iEiViBRMM" (merged memory), or a number (the number of available
bytes in user memory for port 0, or in the port’s independent
