Description
Each entry_item may have a field in a database file associated with it. The data_field identifies the database field from which data is to be stored, retrieved, and cleared. Data_fields are most often set by the entry_item command.
entry_item customer.name
They may also be set using the data_field message. This may be done if an entry item needs to be set to another field number than the initialized one. Data_field numbers begin with 0 for recnum and count up to the number of fields in the file with which the item is associated. Values outside this range are errors.
set data_field 0 to 4
get data_field 0 to var
If the entry_item is not associated with a data field (it is associated with an expression or variable), the value of this property is 0.
