Mike, it's just as easy (and readable) to code this

DCL    &SQ *CHAR 1 VALUE('''')     /* Single Quote (') */

but this version has the advantage of being portable.  I know that
portability is not particularly an issue now, but who knows?

In RPG code, where portability can already be an issue, this is more
important.  If you have other characters like tab, it might be a good
idea to make a single /COPY file with named constants for these special
characters.  Then there's not much to choose between '''' and x'7D',
since you have several things to change if you go to a different system.
