The TAB keyword controls vertical positioning in the LAYOUT command by separating sets of controls and labels in multiple columns by tabs so that the entries in each row line up directly below the entries in the row above.
Example
GROUP "SQL Server Schema Check Constraint" { LAYOUT { TAB ALIGN Over COLS 2 } PROPERTY "SQL Server Check Constraint Name" { EDIT Text LENGTH 30 Label "Constraint Name"} PROPERTY "SQL Server Check Constraint" { EDIT TEXT LENGTH 256 LINES 10 LABEL "Constraint Check"} } REM "End of Schema Check Constraint group"
