Lots of options stylistically.

Personally, I dislike underscores so I tend to lean towards cnYES or cnNO. I don't use "cn" on my standard True/False.

Whatever floats your boat. Consistency is of higher importance to me anyway.

We had a contractor recently who, in 3 IF statements in the course of about 15 lines, managed to case it 3 different ways - drove me NUTS.

THAT.... did not float my boat.

Thomas, others have addressed the syntactical part of your question, but
I have a stylistic suggestion.  Rather than using variables x_yes and
x_no, I prefer to use constants:

dcl-c C_YES 'Y';
dcl-c C_NO 'N';

My own preference is to uppercase literals and precede them with C_;
that makes it very clear when I use a literal.  Then I can write the

if xzstas <> C_YES and xsstas <> C_NO;

The code in the if will be executed if xzstas is anything other than 'Y'
or 'N'.

How do I get x_yes set to 'Y' and x_no set to 'N';

Then I have the following if statement.

if xzstas <> x_yes or x_no;

xzstas is an alpha A1.

I am getting a RNF7421.

What is wrong with my operation? I am supposing the "<>" is not correct.
