Hi, guys,
when compiling the example below the error occurs
"Error E0047 Code block contains both macro and declared symbol references"
the last line
to remove the line LOCATE error "disappears"

Mario

<CODE>

#include "hbclass.ch"

PROCEDURE Main( )
RETURN

CLASS test

METHOD Locate( cExp )
ENDCLASS

METHOD Locate( cExp ) CLASS test

Select( ::nArea )

LOCATE FOR &cExp // coment this line

RETURN Self

STATIC FUNCTION EarlyFieldBlock( nField )

return {|Self, xVal| IIF( PCount() == 2, ( Self:nArea )->( FieldPut(
nField, xVal ) ), ( Self:nArea )->( FieldGet( nField ) ) ) }

You have to use

LOCATE FOR &( cExp )

Changes was needed on startup functions due new gcc versions that was not
loading correct the symbols

Dear Luiz,
I recently received notifications from SF of changes to xHarbour which I
did not see any notification on the Developers Group.
Could you please describe the changes? When changes of this scope take
place I believe it is important to describe to the group what the change is
about, what new functionality it adds, or problem it solves. This is true
even for BORROWED code, because many might not follow Harbour and have no
clue what such code changes intend to achieve.
Also, please make sure that all changes are reported on this forum.
TIA,
Ron

Luiz,

Please provide more detailed info. Almost everyday I get new emails about
compile errors, "code block contains both macro and a declared symbol" on
perfectly valid code which does not even have any macro!!!

I now also get emails about simple INLINE Methods that always worked, now
raising RTE about invalid argument.

We can not afford this kind of low level instability! People are begining
to "fix" perfectly valid code, and this ends up causing real RISK.

Please take the time to EXPLAIN the exact nature of the changes, in
DETAIL!!!

Ron

Ok, I just get this sample from Patrick on comp.lang.xharbour:

FUNCTION Test()
LOCAL cTemp
SET FILTER TO &cTemp
INDEX ON field->TEST TAG TEST
RETURN NIL

I always used

SET FILTER TO &( cTemp )

to avoid the error. But I just test the Patrick sample using Harbour and
there is no error.

I must apologize, it may be related to a change I made Aug 15.

I am currently reviewing.

The issue of RTE on INLINE Method is SEPARATE, and someone should forward a reduced sample.

I just request a sample in comp.lang.xharbour. Let's hope someone has one...
