The Occurrence Number
Many statements allow you to specify which occurrence of a multi-occurrence field you want to compare or operate on. For example:
TT IF TGL COUNT 001 EQ TGL COUNT 002
The left-hand field in this example refers to the first occurrence of the field COUNT in the TGL application, and the right-hand field refers to the second occurrence of the field COUNT. You indicate if a field is to have more than one occurrence as a specification in the data dictionary.
