Application Development (the resource worksheet file) Step 4 It was necessary to link the "Resource Record" menu to each unique resource record. The linking permits the secondary menu associated with each resource to be displayed on the monitor after the execution of the first &ILOAD macro has displayed the initial resource specific image on the graphics screen. The linking of the two macros was accomplished by "chaining" the &ILOAD macro command that is activated from the mapped graphics screen with an additional macro statement. Example: Cell [F4] is the location of the image load (&ILOAD) macro for the initial image associated with the Sunrise Lodge. The following macro statement was appended to the end of the image load macro command. &LOADG RSUN &BRANCH K2 The resulting chain of macro statements in cell [F4] is this: &ILOAD RSUN1.TGA &LOADG RSUN &BRANCH K2 The component parts of the macro chain are: [&ILOAD] Image Load Macro [RSUN1.TGA] Image filename to be loaded [&LOADG] Load a specified [.CRS] file into the Global worksheet [RSUN] This is the [.CRS] worksheet file to be loaded into the Global worksheet environment. The worksheet extension [.CRS] does not need to be included in the file specification since it is the default worksheet filename extension recognized by CRISTAL. [&BRANCH] Continue execution of a macro statement at a specified cell location. [K2] The cell location of the macro statement to be executed by the &BRANCH command. In the MORA application, the &MENU macro statement is located in cell [K2]. This macro statement must follow each resource label in the primary worksheet. The application authoring process was expedited by copying the same macro statement for each resource record included in the system. After copying, the filename for the image and worksheet specifications was changed to correspond to the unique filenames assigned to each resource record for Mt. Rainier National Park.
