Zugg Software :: View topic - [1.34] #VAR $var {...} broken; cannot create variables named with $vars.

#ALIAS working {
var = "Foo"
#VAR @var {Bar}
#ECHO @Foo
}

The output of running this is, as expected, 'Bar'. The @Foo variable is created (as is the useless @var variable)

Now, the smart programmer would try to take advantage of the new temporary variables to streamline the code:

#ALIAS broken {
$var = "Foo"
#VAR $var {Bar}
#ECHO @Foo
}

Not so good. The output is a blank line, because the @Foo variable is not created. In fact, #VAR tries to create a variable with a blank name.

Not a bug - the #var command can also be used to directly edit the values of local variables. To edit a variable named dynamically with a local variable, use

#var %eval($local) {value}

as in

$test=olol;#var %eval($test) {wow};#say @olol

I guess this is another thing that needs adding to the help.
