Remarks

Syntax 1: Browsing the control elements

This syntax is used to browse all the rows, visible or not, of a List Box, Table or Looper control.

For each row browsed:

<Control name> returns the subscript of the current row. <Index> can also be used to find out the subscript of the current row.
<Control name>[<Control name>] returns all the columns separated by TAB characters. This syntax is equivalent to <Control name>[<Subscript>].
<Column name> returns the column value for the row currently browsed.

The browse has no effect on the current selection.

The behavior is undefined if the number of control elements is modified during the browse.

Syntax 2: Browsing the selected control elements

This syntax is used to browse all the selected rows, visible or not, of a List Box, Table or Looper control.

For each row browsed:

<Control name> returns the subscript of the current selected row. <Index> can also be used to find out the subscript of the current selected row.
<Control name>[<Control name>] returns all the columns separated by TAB characters.
<Column name> returns the column value for the row currently browsed. You can also use the following syntax: <Column>[<Subscript>]

Change of behavior in version 12: Before version 12, the browse operation had no influence on the current selection. From now on, the current row in the table is always moved during the browse.

The behavior is undefined if the number of control elements is modified during the browse.

Browsing the rows of a Table control

When browsing the rows of a Table control:

the display of this Table control is locked. MultitaskRedraw is ignored.
the selected rows and/or the current row must not be modified (TableSelectMinus, TableSelectPlus, ...).
for a browsing Table control, in the browse loop, the current record is the record processed by the browse.

Reminder: The Table controls are not available.
