Figure 7.11 Local Variables in a Formula
Note: You can also create local variables using the button on the on-screen keypad. Clicking this
button creates a local variable with a default name in an expression and places a semicolon after it. The
default name is t1, and additional local variables are named t2, t3, and so on. You can change these default
names by double-clicking and editing the name. However, you must be careful to rename each instance of
the variable to avoid errors.
Use the Munger Function
The following examples show uses of the Munger function. In these examples, assume that there is a
character column of names with “Veronica Layman” as one of its values. To simplify the examples, the literal
name “Veronica Layman” is the search string instead of a column name.
For instructions on how to incorporate Character functions, such as Munger, into a formula, see
“Character Functions” on page 402 in the “Formula Functions Reference” appendix.
Insert Characters
This Munger example finds the blank between the first and last name, and inserts the middle initial “J.”
The formula Munger("Veronica Layman", 1, " ", " J. ") inserts the middle initial J., and evaluates as Veronica
J. Layman.
Double quotes are required by the Munger function for literal strings, including strings that consist of a
blank or when leading or trailing blanks are part of a string.
Delete Characters
To delete one or more characters from a string:
1. Designate the characters to delete as the Find string in the Munger function.
2. Enter an empty Replace string: two quotation marks with nothing between them.
For example, the function, Munger("Veronica Layman", 1, "onic", "") removes the “onic” from Veronica
and evaluates as Vera Layman.
