Hi,
I'm writing a KSH script, and at one point, I have to call a new shell and perform some variable assignments.
I noticed that the assignment is not working.
Please see two samples below:
Command 1:

A="$( echo -e "\na\nb\nc\n" )"then I get
a

I have a little code block (executing on AIX 7.1) that I cannot understand why the NOTFREE=0 does not appear to be assigned even though it goes through that block. This causes a unary operator issue.
