Clarion in general: Memcpy to get a value from an address 2004-03-11 -- Paul Attryde Newsgroups: softvelocity.clarion.language

So you're doing something (making an API call for example) and getting
back a pointer? But because CW doesn't support pointers you can't
dereference it?
There's a couple of ways to do it.
You can do what Bernie suggested and use a reference variable (but that
assumes you're using a version of CW that supports reference variables,
and this is softvelocity.clarion.language, not softvelocity.public.clarion6)
Personally I use memcpy, only because I've been doing this for a while
and CW2 didn't have reference variables :)

ISTR Randy Goodhew saying you can do it using PEEK as well, but I've
never used that. You may have to search the NGs for more info.
