using function

[Rskm]

Hi, I wrote the below code to learn user defined functions.. jam is the function which calculates summation and division of two numbers $a, $b.. I expect the $sum and $div receives the results $r and $s respectively from the function... but the msbox in the main program doesn't display results properly, while the one inside func shows it correclty. how do I pull the values in $r and $s to $sum and $div respectively.. thanks for all the help on this forum

 

global $a,$b,$sum,$div

$a=1
$b=2

jam($a,$b,$sum,$div)

msgbox(0,"results",$sum&" , "&$div)

 

 

func jam($p,$q,$r,$s )

 $r=$p+$q

 $s = $p/$q

msgbox(0,"results",$r&" , "&$s)

EndFunc

Just replace your func parameter definition by:

func jam($p,$q, ByRef $r, ByRef $s )

and welcome to the forum.

Try to avoid Global vars

Local $a, $b

Should be enough.

Interestingly, variables declared at the main level are always scoped as global, so it is less confusing to declare them as global. Try this:

Opt('MustDeclareVars', 1)

Local $ttt = "hello"

VarTest()

Func VarTest()
    MsgBox(0,"debug", $ttt)
EndFunc
