function, using the string expression attribute
, retrieves a setting from an attribute-value pair, a setting that has been previously saved using the savesetting
function. An optional string expression default_setting
can be provided and will be returned if no value has been saved for the given attribute.
The location from where settings are retrieved can be modified by altering the CommonStore attribute of a PFF file.
The function returns a string containing the value associated with the attribute. If no value is associated with the attribute, then the function returns a blank string unless a default setting has been provided, in which case it returns the default setting.
