My advice, for dealing with these limits, is "when in doubt -- don't". If you might exceed the maximum size of an array, don't use an array! Tweaking it into working "for now" without solving the limits problem anywhere else is a temporary solution at best.

These limits are heavily shell and system specific, not just the kind of shell but the branch (there are several 'kinds' of ksh) and version. Making a script which abuses these limits could strand it on your system.

There is also a tendency to use shell arrays as a hammer -- when all you have is a hammer, the world looks like a nail. In many cases these are suboptimal and never required arrays in the first place, there may be more appropriate solutions to whatever you're doing.

So please explain what you are doing -- and do NOT say "trying to make a bigger array"! What is this array holding? Why do you need it?
