Does pdksh (public domain kornShell) support associative arrays?
Question
I recently ran up against a wall doing some bash shell programming where an associative array would have solved my problems. I googled about features of the KornShell (ksh) and learned that it supports associative arrays, so I installed Cygwin's pdksh (Public Domain KornShell).
However, when trying to create an associative array in the prescribed manner (typeset -A varName), I received the following errors, so I'm beginning to suspect pdksh does not support associative arrays.
./find_actions.ksh: line 2: typeset: -A: invalid option
typeset: usage: typeset [-afFirtx] [-p] name[=value] ...
Guess I will be considering Perl instead, but I really wanted a good excuse to learn a dialect/language new to me.
Solution
Take a look at ksh93, it supports associative arrays and is a much more complete/correct implementation of ksh.

OTHER TIPS
pdksh doesn't have any support for associative arrays; it’s a planned and definite feature of its successor, mksh (as soon as I get around to actually implementing it, that is… sorry for being slow with that).
Why not just use bash? It might not have explicit associative arrays, but you can fake them.
Alternatively, zsh has excellent associative array support.
