Progress 4GL Reference

BUFFER-VALUE attribute

The current value of a buffer-field object. If you modify the BUFFER-VALUE attribute, Progress sets the buffer-field object to the new value.

Data type: The data type of the corresponding buffer-field

Access: Readable/Writeable

Applies to: Buffer-field object handle

Syntax

BUFFER-VALUE [ ( i ) ]

i

An INTEGER expression representing a subscript, for fields that have extents.

The syntax for retrieving the value of a buffer-field object using a dynamic reference to a table field in a dynamic ProDataSet, Temp-table, Query, or Buffer object can be awkward, especially when you know the table and field names at compile time. Progress provides a simpler way to express the same syntax, only in a short-hand form. For example, following is the typical syntax for referring to the Cust-num buffer field in the Customer table through a ProDataSet handle:

hDSet:GET-BUFFER-HANDLE(“ttcust”):BUFFER-FIELD(“Cust-num”):BUFFER-VALUE

Following is the short-hand form of the same syntax:

hDSet::ttcust::Cust-num
