Calling Paramacro Variables with the CALC Function
Expression Entered Result Displayed
#100 Display current value of variable #100
12/#100*3 Divide 12 by the current value of #100
and multiply by 3
SIN[#31*3] Multiply the value of #31 (for the current
local parameter nesting level) by 3 and
take the sine of that result
We use the term softkey to describe the row of 7 keys at the bottom of the
CRT. Each function is displayed on the CRT directly above the softkey.
Softkey names are shown between the { } symbols in this manual.
The control offers a variety of functions that can be initiated by using the
softkeys. The operator panel has 5 softkeys whose function names are
displayed in the softkey area at the bottom of the screen (lines 23-25 — see
Figure 2.3).

We often describe softkeys as being on a certain level, for example softkey
level 3. We use the level of the softkey to determine the location or
necessary path to reach that particular softkey function. For example, to
get to a softkey on level 3, you must press a specific softkey on level 1,
followed by a specific softkey on level 2. For a listing of all the softkeys
and their respective levels, refer to appendix A.
