I'm trying to create a variable with a name that contains a variable. I've been able to do this in the past I think, but I can't remember how. After two hours of searching, I figured I'd ask you folks. Maybe you can refresh my memory. :)

Trying something like:

#var @charname_worth {123456}

Hoping to create a variable named "Rahve_worth", that equals the value given.

I thought I remembered doing it like this, in the past:

#var {@charname}_worth {123456}

But that didn't quite work. Any ideas folks..?

Looking at the Help files for Parsing, would this work?

#VAR @{charname}_worth 123456

Actually that does work, but for some reason it creates the variable WITH the brackets surrounding it.

Ex - that variable is labelled {Rahve}_worth

Any idea how I can get rid of the {}'s from the final product..?

#var [@charname]_worth {123456}

[] forces the command to expand @Charname before creating the variable. @{charname} shows #var where the name of the variable ends.

Cool, that did work, thank you. I have a very complicated command I use to calculate my worth and tax etc on my MUD, and I'm trying to get this to create a variable set for each char that gets the worth told to them. It works just fine with the @charname's stripped, but I can't get it to parse the NEW variable name, including the char's name. Any ideas how I can do this..?

#say Worth at last EW: %eval( (@{charname}_st_worth) / 1000000)M - After Tax: %eval( (@{charname}_st_taxworth) / 1000000)M - Tax Total: %eval( (@{charname}_st_tax) / 1000000)M ~{@floatingpoint_percent( %eval( 100 * %float( (@{charname}_st_tax)) / %float( (@{charname}_st_worth))))~%~}

The [@charname]_worth set was barked about by the settings editor, and didn't seem to work in the command line either.

When in doubt, test for yourself. After a couple minutes of experimentation, I have the following results. Variable names and values were checked by entering just the #VAR command. All experiments were done both from the command line and from an alias, with identical results. Except for @charname, variables were deleted after each test.

#VAR charname Rahve
Creates a variable named charname with value Rahve

#VAR @charname_worth 123456
Does nothing

#VAR {@charname}_worth 123456
Creates a variable named {Rahve_worth} with value 123456

#VAR @{charname}_worth 123456
Creates a variable named Rahve_worth with value 123456
NOTE: The variable with the brackets surrounding it was a holdover from your earlier attempts, not from this syntax.

Additional experiments:
#VAR [@charname]_worth 123456
Creates a variable named Rahve_worth with value 123456

#VAR <@charname>_worth 123456
Creates a variable named Rahve_worth with value 123456

I probably wouldn't use any of these. Record variables are simpler.
#ADDKEY worth {@charname} 123456

Thanks, LB!
