HP 49g Graphing Calculator - Manual (Page 108)

Deleting a library
To delete a library from a port, use the following commands. In the
commands, port^number is the number of the port you stored your
object in and 1 ib_number is the library number of the library you want
to purge.
® In RPN mode:
:port_number: lib_number PURGE
• In algebraic mode:
PURGE(;port_number: lib_number)
How the HP 49G manages memory
The following section explains how the calculator manages memory in the
various ports.
Port 0
Port 0 and the HOME directory share the same memory space. This means
that objects stored in port 0 decrease the amormt of user memory
available, and objects stored in user memory decrease the amormt of
memoiy available in port 0.
Port 1
Port 1 contains 255 Kb of storage space. Because of the way port 1
memory is structured, you cannot store objects larger than 128 Kb. This is
because port 1 memory is in fact 2 discrete areas of 128 Kb. Objects must
be stored in either one of the two areas.
Because of this, when storing large objects it may appear that you have
enough memory in port 1 to store your object, but the calculator will not
allow you to store the object if it is bigger than the free space in either
area.
