Re: Free format question on D specs

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 following:

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.
