*ALL is optional. If *ALL is specified and the name operand is a multiple occurrence data structure or a table name, all occurrences or table elements are reset and the occurrence level or table index is set to 1.
The name operand specifies the variable to be reset. The particular value for this operand determines the reset action as follows:
Single occurrence data structure
All fields are reset in the order in which they are declared within the structure.
Multiple-occurrence data structure
If *ALL is not specified, then all fields in the current occurrence are reset. If *ALL is specified, then all fields in all occurrences are reset.
Table name
If *ALL is not specified, then the current table element is reset. If *ALL is specified, then all table elements are reset.
