I am unable to reproduce this behaviour with global variables. This is
what I've tried among others:
if $/zz % 3 == 0 or $/zz % 3 == 1 then {
set $/zz = $/zz + 1;
action(...)
} else {
set $/zz = 0;
action(...)
}
Could you please explain how is it supposed to work?
It's supposed to work just as you describe it. But indeed, it doesn't do
so, I can reproduce the problem. Looks like a regression. Thanks for
reporting, will now look into it.
OK, looks like I stumbled into my own trap. In script, you access
properties via $<propname>. Global variables have the name $/zz (with zz
being the real name). So to access them, you need to access $$/zz.
I think I got confused about this some time ago, and the doc is also not
correct or at least inconsistent. I now need to work my way through that
mess. Just thought I give you some explanation.
Ouch, this is going to get ugly since $$var actually ends up giving you a
reference to $var not it's value, I believe from prior discussions that the
normal variables are $property of $!var!var,
That previous discussion was wrong, it is $$!var!var - and it does not give
the ref to $var, but it's value.
hmm, I had a problem where I was trying to set var2 = $$!var1 and then delete
var1 and the result was that once var1 was deleted, var2 had no value, if var1
wasn't deleted, var2 had a value. when I posted about it, I was told to change
$$ to $ (I'll have to go back and dig up the e-mail for the exact syntax that I
used), and changing to a single $ on the right side caused everything to work
properly after var1 was deleted.
