System Flags
System flags provide you with some control over how the HP 49G behaves
and displays infomiation. For example, by setting flag
-60,
you can lock
the alpha keyboard by pressing
(SM)
once rather than twice. Clearing flag
-60
retimrs the mode to its default setting (where
(IPHA)
must be pressed
twice to lock the alpha keyboard).

Press FLAGS.
The System Flags list is displayed. A tick
to the left of a flag number indicates that the flag is set. If the space to
the left of a flag number is empty, the flag is clear. Fi'om this screen
you can set or clear any flag in the list.
The System Flags list is not a list of all the system flags. As a general rule,
flags that are likely to be changed often can be set or cleared on various
input forms, where they are more readily accessible. Flags that will rarely
be changed are listed in the System Flags list.
For example, flag -95 deteraiines whether the calculator is in algebraic or
RPN mode. As this is a flag that many users are likely to want to change
from time to time, it is accessible from an input form; the Calculator
Modes input fonn (described in chapter 2 of the User’s Guide}. Because it
is accessible from an input fonn, flag -95 is not listed in the System Flags
list. (There are some exceptions to this general rule, with some flags
accessible both from an input form and from the System Flags list.)
All the system flags—not just those on the System Flags list—are listed
and described in the HP 49G Pocket Guide.
