Using Substitution Strings

You can use substitution strings in Application Builder in the following ways:

• Include a substitution string within a template to reference component values

• Reference page or application items using &ITEM. syntax

• Use built-in substitution strings to achieve a specific type of functionality

Special substitution strings available within a template are denoted by the number symbol (#). For example:

#ABC#

To reference page or application items using substitution variables:

1. Precede the item name with an ampersand (&).

2. Append a period (.) to the item name.

For example, you would refer to an application item named F101_X in an HTML region, a region title, an item label, or in any of numerous other contexts in which static text is used, for example:

&F101_X.

Notice the required trailing period. When the page is rendered, Application Express engine replaces value the substitution string with the value of item F101_X.
