The documentation would be located in the SQL Reference Manual

OK, so you're saying that I shouldn't be trying to look for
documentation on something unique to stored procedure syntax. Rather, I
should just look for documentation on standard built-in SQL functions.

Yeah, for the most part, SQL stored procedures use the same concepts
that say, CREATE VIEW uses. To my mind, it's a bit like CL. CL on the
command line is like SQL from STRSQL et al. CL in a CLP allows things
like DCL, GOTO, etc. that can't be used on a command line. Likewise,
SQL allows control statements like IF, RETURN, and WHILE in an SQL
procedure, but not in STRSQL.

OK,
so let me ask the question this way... Where do I find documentation for
syntax or usages that are unique to SQL stored procedures?

The Redbook that was mentioned is a good read, but the canonical
reference for SQL control statements is:
