HP 49g Graphing Calculator - Manual (Page 223)

InsuFRclent memory
Insuf f icient memory is displayed if there is not enough memory to
complete an operation.
Solutions:
1. Try to do the calculation or operation in a way that would use less
memory. (For example, use the factorial command instead of entering
a string of consecutive integers each separated by the multiplication
sign.)
2. Delete imwanted objects from history or from the stack.
3. Delete imwanted variables.
Out oF memory
Out of memory is displayed when the calculator nms completely out of
user memory. In this state, the calculator is capable of only one operation;
a one-by-one interactive purge. In this operation, you are asked if you
want to purge—that is, delete—a series of objects, starting with the object
on level 1 of the stack. If you agree—^by pressing
(ED
—you are then asked
about the new level-1 object. This continues imtil either the stack is empty
or you respond to a request to purge an object by pressing (F6) (for NO).
The calculator then asks if you want to delete other items. All togetlier,
the items you will be asked to purge are:
® the object on level 1 of the stack (repeated imtil there are no objects on
the stack or until you press (£6) when asked to purge a particular stack
object)
® the contents of LAST CMD
® the contents of LAST STACK (if active)
® the contents of LAST ARG (if active)
® the variable PICT (if present)
® user key assignments
® alanus
® the entire stack (unless already empty)
® each global variable.
After cycling through the list of purgeable objects, the calculator attempts
to return to nomial operation. If there is still not enough free memory, the
purge process is repeated.
