Build field names list ([Clear list][,Full names]) {file-name}
| Clear list | If specified, the command empties the current list, and defines it to have a single hash variable column, before executing |
| Full names | If specified, names in the list are prefixed with their file class name |
This command builds a list of field names for the specified file class in the current list. You must specify the following columns in the current list.
| Column 1 (Character) | Column 2 (Character) | Column 3 (Character) |
|---|---|---|
| Field name | Field type and length | Description; for index fields only |
When you use the Clear list option you get column 1 only defined as #S5. With this option the command becomes reversible. The flag is cleared if the value of LIST.$linemax prevents a complete list from being built.
The Full names option creates a list in which the fields are prefixed with the file class name, for example, PO_DATE becomes FPORDERS.PO_DATE.
