Note that this keyboard is similar to other “typewriter” type keyboards used
throughout the CVIM2 user interface, with the exception of the second and
third rows of keys. These keys provide the gateway to the formula–building
math operators and operands. The remaining keys provide the usual alpha
and numeric entry and control functions, as described in Chapter 2, CVIM2
System Configuration: An Overview, on page 2–14.
NOTE: A formula cannot exceed 127 characters, since that is the length of
the formula entry input buffer.
The second row keys operate as “macro” keys, in the sense that they enable
you to enter formula components from lists in several panels, thus using
fewer keystrokes. Here is a brief description of the second row keys:
•
Results key –– The key accesses the Results panel, which lists
all of the tools that precede the math tool in the toolset edit panel. When
you select one of these tools, it will supply to the formula its results from
the current inspection.
