branch; that is, the branch is executed only if the test
condition is met.

Testing for Set Flags and Set Bits
Additional tests for conditional branching are provided by the
(flag set?) and (bit set?) functions. Following these
instructions—as with the other conditional tests—program execu-
tion follows the “Do if True” rule (illustrated above): it proceeds
sequentially if the flag (or bit) is set, and skips one line if the flag
(or bit) is clear.
As discussed in section 3, the flag numbers and their meanings are:
0
1 User flags (used to control programming).
2
3 Controls display of leading zeros.
4 Carry or borrow condition.
5 Out-of-range condition.
Although flags 4 and 5 are set automatically by the calculator, the
user can also set them. If you set flag 4, the carry bit is set to 1.
Refer to section 3 (page 36) for a full discussion of setting flags, and
section 4 (page 50) for a full discussion of setting bits.
