Is there a way to dereference a local variable?

Magician Joined: 17 Apr 2005 Posts: 496

#var $myvar {whatever}

to assign

@{$myvar}

to view.

i thought it was:

#VAR %eval($local) {value}

Oops, yeah, sorry, shalimar is right. I bet you could use %expand($local), too, etc.

You don't even need the %eval. I think that even

#VAR ($local) {value}

will work. The () tells CMUD to evaluate an expression.

I've had to use %eval(). () was not enough.

I still cant figure out how to do the #SAY operation.

#VAR varname 1
$temp = varname
#SAY %eval($temp)

outputs:
varname

%expand fails with temp variables.

not sure how else to do it.

got it nevermind

#SAY %eval(%concat("@",$temp))

works

Don't you mean

#say @{$temp}

?

yes actually that works wonderfully!

is there a convenient way to assign values to the target of $temp?

some sort of %eval($temp) = 1

(this doesn't work however)

I think #var is as convenient as it gets for assigning stuff, sorry.

yeah the only problem with using the #VAR statement is that I'd have to know what the default value for the variable was before I'd overwrite it... and I don't think there's a function that retrieves that information.

If you just use

#var whatever {value}

it won't overwrite any default that whatever has (if it does indeed have one).

Gamma Ray's right, the default isn't changed if it's not specified.

You can access the default using CMUD's COM interface, which isn't documented, but is very similar to zMUD's. It'll look something like %session.GetVar(varname).Default, but I haven't tested that. There are other posts on the forums about it, anyway.
