How can I use 'concat'-ed variables in loops?
|
Yes, the subject is strange. It's a difficult problem to put into a single sentence.
Basically, I have a list of variables that start with 'cures', for instance, @cures_bob or @cures_frank. Now, I have a single alias which I want to refer to any of these variables, given the correct parameters. Basically, %1 will equal 'bob' or 'frank' and I want it to refer to the respective 'cures' variable in #FORALL and/or #LOOPDB commands. So, I want to enter 'bob' into this alias and have it come out with #LOOPDB @cures_bob {Etc} and actually work.
So, I figure, I'll use the %concat function! Nope. Doesn't work. If I concat '@cures_' with 'frank' I just get... '@cures_frank' as text, not actually referencing the variable itself. I have found one single way to make this work and it goes like so:
| Code: |
| %exec( @%concat( cures_, %1)) |
For some reason, this seems to make zMUD reference the variable rather than the text. However, for some unknown reason, this method has... apparently... stopped working. The thing is, it was working fine up until about three days ago and has now stopped working. I have not changed a single thing in zMUD or my PC. However, that oddity aside...
I would really like to know if there is a better way to make this work. Any and all help would be vastly appreciated. |

Without knowing exactly what you are doing I can't suggest a better way of doing it. I can tell you that braces are what you are looking for. Also you really don't want the %exec function, you should use the command.
#LOOPDB @{cures_%1} {#EXEC %val} |
