Re: Free format question on D specs

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

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'.
