HI I have just recomplied stable code with V8.60 and and getting error 1244 message("...is passed as a reference that should not be a constant nor an expression") for my clearwin calls

c fails to compile with 1244 message for arguments 2 & 3
SUBROUTINE GET_OS_VERSION(DESCRIPT, MAJOR_ID, MINOR_ID)
c ========================
IMPLICIT NONE

INCLUDE <WINDOWS.INS>
CHARACTER*( * ) DESCRIPT
INTEGER MAJOR_ID, MINOR_ID

CALL GET_WOW_VER@(DESCRIPT, MAJOR_ID, MINOR_ID)
END

c compiles with no messages

SUBROUTINE GET_OS_VERSION(DESCRIPT, MAJOR_ID, MINOR_ID)
c ========================
IMPLICIT NONE

INCLUDE <WINDOWS.INS>
CHARACTER*( * ) DESCRIPT
INTEGER MAJOR_ID, MINOR_ID, MAJOR_ID_x, MINOR_ID_x


CALL GET_WOW_VER@(DESCRIPT, MAJOR_ID_x, MINOR_ID_x)
MAJOR_ID = MAJOR_ID_x
MINOR_ID = MINOR_ID_x
END

I can use this workaround for most of my clearwin calls but how do i handle the situation where i am passing a function reference

SUBROUTINE SET_CWP_FOCUS_MONITOR(IMODE, STM_FOCUS)
c ================================
IMPLICIT NONE
INCLUDE <WINDOWS.INs>
INTEGER IMODE
INTEGER STM_FOCUS
EXTERNAL STM_FOCUS
IF (IMODE .EQ. 0) THEN
CALL ADD_FOCUS_MONITOR@(STM_FOCUS)
ELSE
CALL REMOVE_FOCUS_MONITOR@(STM_FOCUS)
ENDIF
END

in all of these example i am only passing reference so there should not be an issue or am i missing something simple

HI
just a follow up to my previous post

if change the definition in clearwin.ins from

C_EXTERNAL ADD_FOCUS_MONITOR@ '__add_focus_monitor'(REFF)
to

C_EXTERNAL ADD_FOCUS_MONITOR@ '__add_focus_monitor' (REF)

the error message disappears

Am i safe to assume that the new argument descriptors (reff, ref2,val3 etc.) are used to help the compiler identify possible issues but the older type (ref, val etc.) will still work but without the type checking

the clearwin routines i that were giving errors were
GET_GRAPHICAL_RESOLUTION@
GET_GRAPHICS_SELECTED_AREA@
GET_CURRENT_DC@
GET_WOW_VER@
ADD_FOCUS_MONITOR@
REMOVE_FOCUS_MONITOR@
ADD_ACCELERATOR@

thanks

steve

Steve,

you might want to look at request "Compiler error GET_IM_INFO@", 64-Bit forum

http://forums.silverfrost.com/viewtopic.php?t=4136

where the hint is given to use option
Code:

/ignore 1244
.

Regards,
Dietmar
