Conditional Sections
Shown as the last section in the preceding graphic, the conditional section can be called from any of the previous level-one sections using the Do Custom Section system function. Conditional sections are called from a level-one section dependent on the criteria that you defined. For this reason, conditional sections are considered level-two sections. Memory allocation for conditional sections occurs at the beginning of a section. Therefore, you need to place conditional logic in the Initialize Section or End Section event to hide and show objects because memory is allocated and freed only once instead of each time a section is called.
Custom sections appear as level-one sections in the RDA workspace, but they are not processed unless explicitly called by the Do Custom Section system function.
