Just a quick question. I was reading on article on the web and
it stated that if I had a varying fields that what would get
passed by VALUE would be just the first two digits for the length
and the actual length of the data. <<SNIP>>

Can you point to this article you're referring to? I'd like to
understand what you're referring to. <<SNIP>>

Old article by Bob Cozzi and now I can't find it again. Maybe
somebody else can find it.

<<SNIP>> I know it always passed the whole thing but Cozzi was
saying that it only passed the actual length which made no sense to
me.

I too was going to ask what was the source\reference; as a web-based reference, that seeming only natural to have included. But before posting that question, I tried to find the probable article. What I found with my first web search using restrictive search tokens ["by VALUE" "varying fields" "procedure" "call" "rpg"] based on the text from the OP, had located just three articles of which only one was probable, and that was one by Bob Cozzi [I did a cursory review of the cached version of text, from Google, not of the PDF]:
<http://www.nemug.com/handouts/Procedures%20and%20Parameters.pdf>

I continually expanded the search [most notably, cutting "varying fields" to just "varying"] and found several other articles\discussions, but none seemed marginally likely as the original source material. The above article was the only one [of those I chose to peek at] in which I found clearly a mention together of both value and varying; only one article by Jon Paris had an actual code example using both coded together:
<http://www.partner400.com/advancedsubprocs.pdf>

But when I did a /find/ in the text of the cached article [at the first link], searched successively for find strings 'varying field', 'vary', 'by value' and 'value', I inferred nothing from the surrounding context of the article that was similar to what was described in the OP. I decided not to post, pending if\when a post was offered to the original source material. If the above link is the article, then perhaps specifically what text apparently\might [was inferred to] allude similar to what was noted in the OP could be included as a snippet.
