Using append function , string literals truncated at 255 chars

Code:
    String sSelect
    
    Move ""  to sSelect 
    
    Move (Append( sSelect, "SELECT [Type-List#_Seq#], [Alloy_Code], [Product_Code], [Cust_PO#], [Addr#-City], [Length], [Order_Qty], [Picked_Qty], [WEIGHT], [OUTSIDE_PROCESS_NEEDED] = RTrim(OUTSIDE_PROCESS_NEEDED), [Loc_Len_QOH], [Type], [PickInfo] = RTrim(PickInfo), [COMMENTS], [BIRM_LOC]")) to sSelect 
    Showln sSelect
results
Code:
SELECT [Type-List#_Seq#], [Alloy_Code], [Product_Code], [Cust_PO#], [Addr#-City], [Length], [Order_Qty], [Picked_Qty], [WEIGHT], [OUTSIDE_PROCESS_NEEDED] = RTrim(OUTSIDE_PROCESS_NEEDED), [Loc_Len_QOH], [Type], [PickInfo] = RTrim(PickInfo), [COMMENTS], [BI
final string has only 255 chars.

seems ok under df 23.0 ,

was there any hot-fix for this in 19.1 ?
