My version of ksh (1993-12-28 q) doesn't seem to have a limit either. I did a test to assign values to a array in a loop. I gave up at 700,000 elements.

ksh seems to be twice as fast than bash to assign array values. So, I pushed my little benchmark a little bit further and I assigned 10,000 values to an array and randomly accessed that array 1000 times.

Code:
bash
  real    0m0.623s
  user    0m0.500s
  sys     0m0.020s

ksh
  real    0m0.157s
  user    0m0.160s
  sys     0m0.000s

Happy new year to all. Smilie

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
