Re: Free format question on D specs

Stylistically I have wondered why we ever use Yes/No'; we already have the very clear *on & *off.

Why not a meaningful named indicator for each condition being tested?  Something like ItIsReady, WeMayCall, or just Flag1, Flag2,etc.

giving us code like:

    if ItIsReady;
      SendInvoice();
      ItIsReady = *off;
    endif;

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;
