I have the current script with the following code and it works ok.
I want to remove the usage of the following code and replace it with something else since there could be limits as to the size of arguments that a "for" command could take in AIX 5.2 ksh where in this executes.
I could convert the same into something as follows
Please advise me on more alternate efficient methods other than what I have provided above.
Thx

is easier to read than that, especially when the loop is long:
