Re: OPNQRY reference book

This is not specific to OPNQRYF, but when I need to use a single quote ( '
) in a program, I like to fall back on a trick I learned way back in my
Wang Basic programming days: use the hex value. The following code:

DCL    &SQ *CHAR 1 VALUE(X'7D')     /* Single Quote (') */                
                 
                                                    
CHGVAR &MS VALUE(&SQ *CAT 'TEST' *CAT &SQ)          

will produce a value of &MS of 'TEST' (single quotes included in the
value).

This way, I am able to be really clear about when I am looking at single
quotes that are supposed to be _part_ of the string value I am dealing
with, and when I am looking at single quotes that _surround_ the string
value I am dealing with. I never bothered to learn the single quote/double
single quote/triple single quote/(etc.) rules, since this other way always
seemed so much simpler.

Of course, it also works well for any other character (tab, etc.) that is
inconvenient (or impossible) to enter directly into your code. . . .
