I have found that there are two ways that parameters can be passed by reference:
MyFunct1(VarName)
;"Input: VarName, the NAME OF the variable to alter
set @VarName@(1)="Hello"
quit
MyFunct2(VarArray)
;"Input: VarArray -- PASS BY REFERENCE, the array to alter.
set VarArray(2)="There"
quit
And These can be called as follows:
Main
new Array
do MyFunct1($name(Array))
do MyFunct2(.Array)
zwr Array(*)
quit
This should output this:
Array(1)="Hello"
Array(2)="There"
But I have just encountered an issue when I try to mix these two. For
example, The following wouldn't work, I believe
MyFunct1(VarName)
set @VarName@(1)="Hello"
do MyFunct2([EMAIL PROTECTED]) <------------- This wouldn't work
quit
MyFunct2(VarArray)
set VarArray(2)="There"
quit
Main
new Array
do MyFunct1($name(Array))
zwr Array(*)
quit
So I have written some functions using both calling methods, and I
have just now had reason to call one from another.
I know that I could create a new array, merge it, pass that array,
then when the function returns merge it back. But, is there a way to
do this directly--i.e. achieve my erroneous line listed above, perhaps
with different syntax?
Thanks
Kevin
