Sigh. Users Guide. Syntactic rules belong not in a Users Guide
but in a Command Ref., which is where I looked.

And that's JCL. It belongs in the JCL Ref., where it undoubtedly appears.
It shouldn't be duplicated here, except in an example.

"[Copy code]"?
The example might instructively show a trick to concatenate (long) lines with
a command substitution:
//STDPARM DD *
SH /myscript.sh AAAA
BBBB$( : These lines are
concatenated! )CCCC
/*
Is equivalent to:
//STDPARM DD *
SH /myscript.sh AAAA
BBBBCCCC
/*
