Section 14: Flags continue230




USER Mode Flag


This flag (flag 27) is used to place the calculator into and out of USER mode. When
flag 27 is set, the HP41C is placed into USER mode. When cleared, the HP41C is taken out
of USER mode.


You can set, clear and test flag 27 just like a general purpose flag, but keep in mind
that this flag also controls USER mode.


The status of flag 27, whether clear or set, is maintained at all times by
Continuous Memory, even when the calculator is turned of and on.


Number Display Control Flags


Two flags, the decimal point flag (28) and the digit grouping flag (29) are used
to control how numbers appear in the HP41C display.


The decimal point flag (flag 28) controls the radix mark and the
separator mark in a number. A radix mark is the divider between the integer
portion of a number and the fractional portion of a number. The separator mark is the
separator between groups of digits in a large number.


In Europe, and many other international locations, the radix mark is the comma
and the separator mark is the decimal point. So numbers appear like this:
123.456.789,123. In the U.S. the
radix mark is the decimal point and the separator mark is the comma. Numbers appear like
this: 123,456,789.123. The decimal
point flag (28) allows you to use the radix mark and the separator mark with which you
are accustomed.


When flag 28 is set, the decimal point is the radix and the comma is the separator. Numbers
appear like this: 123,456,789.123.


When flag 28 is clear, the comma is the radix and decimal point is the separator. Numbers
appear like this: 123.456.789,123.
