Hi,
Sorry for the all the confusion. I sat down with my senior programmer and
finally got the bottom of the confusion.
It is actually two separate issues that I confused as one due to my lack of
Clipper knowledge.
Difference 1) ordsetfocus() if it cannot find a key you are looking for..
for instance if you run (with a typo) the ordsetfocus("isbnM") (notice the M
typo) twice, when I really was looking for "isbn"... it will return a blank
C string "" the 2nd time, because it cannot find "isbnM". Clipper instead
does not switch it to "", but retains the previously working key.
Difference 2) sx_indexname returned CAPS all the time in Clipper. Also,
with a few more differences. This is the workaround my senior has created
to deal with this.
***************************
FUNC BM_INDEXNAME(x,lNoPath) // SIMULATES THE SX_INDEXNAME() BUT STRIPS THE
PATH
// Harbour SX_Indexname() was not compat with SIX
// Harbour does not covert to uppercase
// Harbour return NIL instead of "" when no index is found
LOCAL CDXNAME:=SX_INDEXNAME(X)
LOCAL NPOS:=RAT("\",CDXNAME)
If ValType(CDXName)="C"
CDXName:=Upper(CDXName)
Endif
IF Valtype(lNoPath)="L".and.lNoPath .and. NPOS>0
CDXNAME:=SUBSTR(CDXNAME,NPOS+1)
ENDIF
RETURN CDXNAME
**********************
I think this will clear up the confusion earlier. I'm sorry for that. :(
But basically with these two things we are having to do, we are finding a
lot of our .PRGs need to be changed. If this now makes sense, could you
recommend some steps for us to take?
