The following diagram illustrates the syntax for specifying remap population items:
<remap population items>
──┬──────────────────┬─<population item name>─┬───────────┬────────────┤ └─ <identifier> = ─┘ └─<comment>─┘
Explanation
Population items can appear in the remap exactly as they do in the data set, they can be included and given a new name, or they can be omitted from the remap.
When only the population item name is specified, the item is included exactly as it appears in the data set.
The name of the population item can be changed by using the <identifier> = option. The new name cannot exceed 30 characters.
Population items that are excluded from the remap cannot be accessed and are not present in the user work area. The system maintains the population item correctly whether it is included in the remap.
Example
The following example illustrates the DASDL syntax for a remap population item:
D DATA SET ( A ALPHA(2); P POPULATION(100) OF E; E UNORDERED DATA SET ( N NUMBER(3); R REAL; ); RE REMAPS E ( N; ); ); RD REMAPS D ( X = P; RE; A; );
