How to determine if syntax array=( str1 str2 str3 ) to declare array is valid

Hi, I am creating a Korn shell script and need to create an array where each element corresponds to one line of an input file. Being able to do the following would be awesome:
array=( $(cat file.txt) )
However, I'm finding that not all of my development boxes allow this. Some return this:
ksh: syntax error: `(' unexpected
I suspect this has something to do with the Korn shell version. Does anyone know how I can find out what version is required in order to be able to declare arrays, as above? Or is this an OS version issue?

I would really appreciate any tips on how I can find out the minimum requirements for this syntax to be valid.

Did not find any specific documentation, but was able to determine from my boxes, that it only works on ksh93. On other versions of KSH, need to use the "set -A array" or "array[index]=..." methods.


array, ksh, linux, shell scripting
