Chapter 8

Defining Strings for Serial Ports and Viewports

8–38

In order to use the

Repeat String

feature, you must define the range (that is,

the

Start

,

End

, and

Increment

values) using the

Repeat String

menu:

Repeat String box

Repeat String menu

In configuring the repeat range for a string, you set the

Start

, the

End

, and

the

Increment

values.

Start value

End value

Increment value

During operation in the run mode, when the string is to be displayed, the
index is set to the

Start

value, then:

(1) If the

End

value is greater than or equal to the

Start

value, the string

is displayed.

(2) The index is incremented (according to the

Increment

value).

The string is displayed for each index value, until the index value exceeds
the

End

value.

The CVIM module thus displays the string for each index value, until the
index value exceeds the

End

value. If the # character is included in the

repeated string, the current index value replaces the # character in the string.

In our example, to display the string 5 times, and include the numbers 1–5 in
the five strings, respectively, we set the

Start

value to 1, the

End

value to 5,

and the

Increment

to 1. The index will increment through values 1 to 5,

printing the string five times. If instead we needed to indicate the numbers
6–10, we can set the

Start

value to 6, the

End

value to 10, and set the

Increment

to 1, so the index will increment from 6–10, and so forth.
