[Help-bash] How to print transformed assoc array index?

[Peng Yu]

Hi,

It seems that the index of an assoc array cannot be transformed. This
seems "address@hidden/1}" to be a valid syntax. Why is it not support? Or I
am not using it correctly? Thanks.

$ declare -A y=([a1]=A1 [b1]=B1 [c1]=C1)
$ echo address@hidden/1}
-bash: A1 C1 B1: bad substitution
$ echo address@hidden/1}
A C B
$ echo address@hidden
A C B
$ echo address@hidden
-bash: A1 C1 B1: bad substitution
