Dialog Box Options

Text with Parameters in Percents (%parameter name%)Specifies the text you want to build. Define parameters by placing text between a pair of percent signs. You can use each parameter only once in the text that you build. To include a percent sign in the output string, you must type the percent sign twice.
Configure ParametersContains the following options:
  • Parameter—Lists all parameters defined in the Text with Parameters in Percents (%parameter name%) section.
  • Sample text—Displays text configured according to the options set in Parameter Properties.
  • Sample boolean—Displays a button configured according to the options set in Parameter Properties.
  • Sample number—Displays a number configured according to the options set in Parameter Properties.
  • Sample result—Displays the value you enter in Sample text, Sample number, or Sample boolean based on the options you select in the Parameter Properties section.
Parameter PropertiesContains the following options:
  • Text—Formats the parameter as a text string.
  • Number—Formats the parameter as a numeric value.
  • Boolean—Formats the parameter as a Boolean value.
  • Format—Provides formatting options for the parameter depending on the data type. Examples of each format appear in parentheses after the name of the format.
  • Use minimum field width—Pads any excess space to the left or right of the text, number, or Boolean with zeros or spaces to reach the minimum width you enter in Minimum field width.
  • Minimum field width—Specifies the width to which you want to pad the text, number, or Boolean. The default is 0.
