You enter a function in a cell in the same way you enter
a formula or any other entry, with a few additional
guidelines.
- Always start the function name with the "at" sign (@),
so NExS recognizes the string as a function. Function
names are abbreviations that indicate what the
function does. For instance, @ABS computes absolute
value, @ROUND rounds to the specified number of
places, and @AVG computes the average of a list of
arguments.
-
After typing the function name, enter arguments in
parentheses. Most functions use one or more arguments
to define the task to be performed. For example, the
@AVG function averages the value of two or more
arguments. The @LENGTH function returns the length of
an argument that is a character string.
- Use only the arguments required by the function, in
the exact order specified in the function syntax. If
you enter other arguments or enter them in the wrong
order, NExS will misinterpret their meaning or return
an error message.
-
All the function names in this chapter are typed in
uppercase letters, but you can enter them in upper or
lower-case for your entries.
