Chapter 8

Defining Strings for Serial Ports and Viewports

8–37

Example 4 – Using Repeat String and # (Index) Character

The first column in the viewport display (Gage 1:, Gage 2:, etc.) was created

using a single viewport string, along with the Repeat String feature.

Example 4

Here are the elements of the data code used to create the string:

• Literal text (enclosed in quotes) is used to display the word Gage and the

“:” (colon).

• The # (index) character, when used as a standalone character (that is, not

as part of a data code), displays the current value of the index. In this

case, used with the Repeat String feature (discussed below) the #

character is used to supply the gage numbers 1–5 for the repeated Gage

string.

• The N (newline) character causes subsequent string text to be displayed

directly below the previous text. In this case, used with the Repeat

String feature (discussed below) the N character is placed at the end of

the string, and is used to display the repeated string in a column, rather

than across from left to right, which is not desirable in this case.

Using the Repeat String and # (Index) Character

Recall that the Repeat String feature allows you to repeatedly display a

string. This is accomplished through the use of an “index” number, which is

incremented through a range of values – you define this range using the

Repeat String menu.
