Subscript is outside defined range (Error 1234)
An attempt was made to reference an array element with a subscript outside of the range defined for the array using the DIMENSION command.
For example, copying a member array to an existing non-member array with certain dimensions using the ACOPY( ) function might generate this error. You can avoid this error changing the dimension of the destination array to a single element before calling ACOPY( ). For more information, see ACOPY( ) Function and DIMENSION Command.
