I have declared the following variables in my script :

#var cstep 1
#var room@cstep %roomexit /* with the room exits string be "n|s|e|h", so there will be a variable <room1 = "n|s|e|h"> */

However, when I enter

#show %pop(room@cstep)

it doesn't show up with the expected "n", but a blank line instead. I know it will show up as expected if I enter
#show %pop(room1)

but the problem is that, the variable @cstep will change with time so that I need to retrieve the directions from e.g, @room1, @room2, @room3, .... etc.

How can I solve the problem ?

P.S. I am using 6.21

This is a beta function (so this should have been on the beta forum) which I can't test, however this is what would work in other functions:
#SHOW %pop(@{room@cstep})

I have tried this also
it behaves the same and doesn't solve the problem

I guess there is no way to expand what's in the brackets in.

#show %pop(room@cstep)

Here's a way to go around it...

#var List1 {a|b|c}


#var List2 {1|2|3}


#var List3 {x|y|z}


#var pop "%if(%isnumber(%1),%case(%1,%pop(List1),%pop(List2),%pop(List3)))"

You can reassign the pop variable to extend the number of lists.

Hope this helps.

If variable expansion doesn't work properly in the %pop function of BETA version 6.21, then since you are a beta tester, you should probably upgrade to the beta version that's currently under test. It's quite likely that this bug has already been identified and corrected. However, if it still exists in beta version 6.26, then please report it in the BETA forum so that Zugg will be aware of it and can correct it. This is why he offers the beta versions for testing, so that he can be informed of bugs he might not encounter in his own testing.

%pop expects a varable name, and doesn't expand it, if it's a name with nested variables, or an array.
I'm not even sure if it's expected to do so.

Definitly a question for the beta forum - it's much more likely to get a good answer there.

Note:
You CAN force expansion by using #EXECUTE
#EXEC {"#show %pop(room"@cstep")"}
but that's rather a 'last resort', then a good solution.
