Description

The config variable modifier is used when declaring a variable to indicate that the variable's initial value should come from a value specified in the configuration settings. If there is no value defined in the configuration settings and no initial value is provided in logic, the compiler will issue a warning message. When looking for the initial value, the case of the variable name must match the case of the attribute defined in the configuration settings.

The config modifier can be used when declaring variables of types:

If no value exists in the configuration settings, numeric values will default to the value notappl and strings will default to "".

Example 1

// if no attribute named "serverUrl" exists in the configuration settings,
// the compiler will issue a warning and the variable's value will start as ""
config string serverUrl;

syncconnect(CSWeb, serverUrl);

Example 2

// if an attribute named "censusYear" exists in the configuration settings, its value will initialize censusYear;
// if no attribute exists, censusYear will start as 2024
config numeric censusYear = 2024;
