Hello Marc, detached locals Here is an explanation from MR. RAO . Thank you, Mr. Rao, for always helping us. Best regards, Otto ____________________________________________________________________________ Creating controls in a loop ...

No. You can not use the loop variable. You need to create the DTPICKER in a separate function in the good old way using the concept of detached locals. for n := 1 to Len( aValues )   nRow += 32   if ValType( aValues[ n ] ) == "D"    ...

Hello, I did this yesterday and the results are the same. Declaration with initialization seams faster. Enrico is right that in a real world program you would not see any differences. In the same source I read that there is also speed differences between passing values by reference or value. Best re...

Mr. Otto,

Try first call to Local2() and after call to Local1()

Hello and thank you for your help. I tested with these changes and see a difference in speed. RETURN NILLocal nMax:= 10000000 STATIC FUNCTION Local1()Local a:= {}Local b:= {}Local c:= {}Local d:= {}Local e:= {}Local c1:= ""Local c2:...

This is NOT a real program, it is a sample. Anyway, it shows two identical values here.

Mr. Otto, Testing: FUNCTION Main()Local nILocal nMax:= 1000000Local nSec1, nSec2Local cSec1, cSec2nSec1:= Seconds()FOR nI:= 1 TO nMax   Local1()NEXTcSec1:= Str(Seconds()- nSec1, 10, 5)nSec2:= Seconds()FOR nI:= 1 TO nMax   Local2()NEXTcSec2:= St...

Teoretically, yes. But I doubt it would make any visible difference in real programs.

Hello Enrico,
I read that declaration with initialization should be 3%-40% more speedy in executing the program.

Could this be?
Thank you in advance

Otto

local aTemp := {}

is equivalent to

local aTemp
aTemp = {}

The advantage is that the first form is more compact, I presume.

Hello Enrico,
Thank you.
But what are the advantages and disadvantages of these two.
With kind regards
Otto
