Did you read the reply?

Here is an interesting bit from the first reply:
If you want to claim that a piece of shell code is running on all
POSIX conformant shells you have to restrict to the subset of features
defined by POSIX.
Limits on maximum array sizes are not even constant withing a specific
shell. AFAIR, you can only rely on ~1000 on ksh88 while on ksh93 you
have 4096 guaranteed (but the limit can be even higher depending on
the version).
(or written for the "POSIX shell"), since another POSIX-compliant
shell might not implement arrays...?
There's no *the* "POSIX shell". There's the POSIX standard and a
couple of shells that support the features defined by the standard.
