Hi All,

I have Updated to the new Version FWH 9.08 and Harbour 2.0
During compilation i get the warning Meaningless use of expression 'Logical'

Example:
REDEFINE BTNBMP ::oBtn[14,1] ID 95 noborder;
RESOURCE "MGET1","","MGET11" OF ::oFld:aDialogs[1] ;
ACTION (IF(oSchl:Formular(oSchl:oSchlDbf), oSchl:BtnUpdate("STAMM"), .T. ),oSchl:oDlg:SetFocus()) ;
TOOLTIP "Formular-Texte" ;
MESSAGE "Formular-Texte in der ausgewählten Sprache"
::oBtn[14,2] := {|| IF(! ::oSchlDbf:lReadOnly .OR. ::oSchlDbf:sprache="DEUTSCH" , .T., .F.)}

this get the warning
ACTION (IF(oSchl:Formular(oSchl:oSchlDbf), oSchl:BtnUpdate("STAMM"), .T. ),oSchl:oDlg:SetFocus()) ;
but this works
ACTION (IF(oSchl:Formular(oSchl:oSchlDbf), oSchl:BtnUpdate("STAMM"), ),oSchl:oDlg:SetFocus()) ;

I will not change my complete sourcecode.
Have you any solution for me

Thanks in advance

Hello,

I think using Your syntax :
IF(! ::oSchlDbf:lReadOnly .OR. ::oSchlDbf:sprache="DEUTSCH" , .T., .F.)
it must be :
IIF(! ::oSchlDbf:lReadOnly .OR. ::oSchlDbf:sprache="DEUTSCH" , .T., .F.)

Best Regards

camelot,

if() or iif() is the same.

But the compiler is correct.
An action like '.t.' is meaningless, because it is no action.
You should write 'NIL' in case the second state of your if doesn't need an action.

ACTION (IF(oSchl:Formular(oSchl:oSchlDbf), oSchl:BtnUpdate("STAMM"), NIL ),oSchl:oDlg:SetFocus())

I agree with Detlef, it should either be NIL or left blank.
