and Operation. The increment and decrement
functions use nnnnn/xxx comparisons to control a running
program in a manner similar to the conditional tests described in
section 7. Each execution of increments nnnnn by yy. In a
running program a test is then made to see if nnnnn is greater
than xxx. If it is, the HP-11C skips the next line in the program
before resuming program execution.

Each execution of decrements nnnnn by yy. In a running
program it then tests to see if nnnnn is equal to (or less than) xxx.
If it is, the HP-11C skips the next line in the program before
resuming program execution.
