9.1.2 Using shortcuts to shorten program entry time
Shortcuts can make program entry easier and faster if the program step memory
to be used for the new program contains the values that you need. Default
reinitialization values are stored in every program step when program memory is
“cleared” by pressing <CLEAR/PROG> <CLEAR/PROG> to reinitialize program
memory. These default values are often what you need.
If a program is already in memory, a new program can be entered into either the
steps that the existing program occupies or into steps that remain unused since
the last reinitialization. In either case, some of the existing data in the steps to be
used may be the same as the new program data. If the is the case, the old data
can be retained more easily than it can be re-entered.
The “shortcut” is simply a one keystroke method of retaining the existing value in
a step when that value is the value you need. For instance, a reinitialized
program step always has a substep 4 (probe #) value of 1. If you are going to use
probe 1 in a step in your program, you can simply retain that value instead of
rekeying the value.
When entering a program, you display substeps sequentially by pressing
<DISP/CNTL>. When you have displayed a substep that contains and displays a
value that is the same as the value you need for that substep, you can simply
retain that value. To retain an existing value in a substep and go on to the next
substep, press <DISP/CNTL> when the step.substep and value are displayed.
Thus the program entry sequence from the table above could be changed to the
following, more efficient, entry sequence. (This sequence presumes that you have
just reinitialized program memory by pressing <CLEAR/PROG><CLEAR/PROG>)
