Re: Varying problems

[Scott Klement <klemscot@xxxxxxxxxxxx>]

Because you're setting the variable to be 5000 blanks with Inz(*blanks)
and then trying to add "Order #:", etc, after that point in the string.

Since the string isn't longer than 5000 chars long, the characters after
the 5000 blanks get dropped.

The point behind varying strings is that you don't fill in every position
in the string with blanks.  You just fill in the area that you need,
and since you don't have all those trailing blanks, you don't have to trim
it, and therefore things run faster.

But, since you're doing a inz(*blanks) you're filling it up with blanks,
anyway...  making it act (in this circumstance) the same way a non-varying
field would.

Also, why are you doing  "@lmsg = @lmsg + ..."?   Why not just do
"@lmsg = ...."?   In other words, why add to the end of @lmsg, instead of
starting from the beginning?   Maybe there's other code that adds text
before that line does?
