passing a function several times?

[deanomeano]

I am using a function in my program to pass a filename variable to a field, but i need to pass it to several fields. I know I could repeat the function for each variable but I also know that I can change where the variable is placed.

Here is the code ;

STATIC FUNCTION FileName
LOCAL cDir := ALLTRIM(CURDIR())
LOCAL cApp := ""

cApp := cGetFile( "*.rpt","Report Files",1,cDir)

IF cApp == "*.rpt"
cApp := "default"
ELSE
IF "\"$cApp
cApp := ALLTRIM(subst(cApp , rat("\",cApp)+1,12))
cApp := LEFT(cApp, LEN(cApp) - 4)
ENDIF
ENDIF

IF !Empty(cApp)
mReportID := Alltrim(cApp)+".rpt"
oReportID:Refresh()
ENDIF
RETURN NIL

What I need to know is, how can I tell my program to change where the outcome is stored without rewriting it for each variable?

Sorry I have not understood exactly what do you want.
Maybe the code below can give you some ideas?

STATIC cApp := ""

STATIC FUNCTION SetRptName()
/*
the body of the function almost the same as the body of your function FileName()
*/
...
RETURN ( NIL )

STATIC FUNCTION GetRptName()
RETURN ( cApp )

maybe this will explain my question better?

CODE ;

STATIC FUNCTION FileName
LOCAL cDir := ALLTRIM(CURDIR())
LOCAL cApp := ""

cApp := cGetFile( "*.rpt","Report Files",1,cDir)

IF cApp == "*.rpt"
cApp := "default"
ELSE
IF "\"$cApp
cApp := ALLTRIM(subst(cApp , rat("\",cApp)+1,12))
cApp := LEFT(cApp, LEN(cApp) - 4)
ENDIF
ENDIF

IF !Empty(cApp)
mReportID := Alltrim(cApp)+".rpt"
oReportID:Refresh()
ENDIF

IF !Empty(cApp)
mFileProof := Alltrim(cApp)+".rpt"
oFileProof:Refresh()
ENDIF

IF !Empty(cApp)
mFinalFile := Alltrim(cApp)+".rpt"
oFinalFile:Refresh()
ENDIF

IF !Empty(cApp)
mReprint := Alltrim(cApp)+".rpt"
oReprint:Refresh()
ENDIF

RETURN NIL

the problem is, they all refresh with the same value, and I want each o:refresh to be able to hold a seperate value?

thanks for any help!

They refresh with the same value because you are assigning to all of them the same value. Try assigning different values and you will get different values.

So, should I have a different LOCAL cApp for each refresh?

[Enrico Maria Giordano]

Yes. Or anyelse assign different values to the different objects.

Many Thanks Enrico.

I think you should rewrite your function such a way that it returns not NIL but cApp. In your main code you will have the following

LOCAL cApp
.....

IF ( !EMPTY( cApp := FileName() ) )
mReportID := Alltrim(cApp)+".rpt"
oReportID:Refresh()
ENDIF
.....

Or you can write general function as for example AssignVal()

FUNCTION AssignVal( &cVarName, oObject )

and call it for various arguments as below

AssignVal( &mReportID, oReportID )
AssignVal( &mFileProof, oFileProof )

and so on.
