See below code. Where are those spaces coming from?!?
More importantly, how do I prevent them?

-DEFAULTH &FOO = '';
-DEFAULTH &BAR = 'B';
-DEFAULTH &BAZ = '';
-SET &CONCAT = &FOO || &BAR || &BAZ;

-HTMLFORM BEGIN
<pre>[&CONCAT|]
-HTMLFORM END
</pre>


The result is:
[B  ]

I'm running into this issue while generating reference ID's in a number of scripts dealing with generating various sections for compound reports. The extra spaces are messing things up!

1. In dialog manager, a variable's value is always at least one character long. So your
-DEFAULTH &FOO = '';
is equaivalent to
-DEFAULTH &FOO = ' ';

2. Hard catenation does not eliminate blanks, it simply moves them to the end of the string.

Thus the length of &CONCAT after
-SET &CONCAT = &FOO || &BAR || &BAZ;
will always be at least 3, and in this case exactly 3.

But you can use TRUNCATE() to drop the trailing spaces.

Hmm... is there anything that a homebrew parser inside a combination of HttpRequestFilter and HttpResponseFilter can't do that dialog manager can? The more I use DM, the more I'm tempted to replace it with something sane.

Does TRUNCATE help you at all?
  
-DEFAULTH &FOO = '';
-DEFAULTH &BAR = 'B';
-DEFAULTH &BAZ = '';
-SET &CONCAT_X = &FOO || &BAR || &BAZ;
-SET &CONCAT   = TRUNCATE(&CONCAT_X);

-HTMLFORM BEGIN
<pre>[&CONCAT|]
-HTMLFORM END
</pre>

TRUNCATE is what I ended up using. I have a LOT of string concatenations in this report-template, so I was hoping I wouldn't need to wrap nearly every concatenation inside TRUNCATE().

I don't think !IBI.AMP works in compound layout definitions? My actual output isn't HTML; I need these variables to generate compound page layout names and such. Most of these variables' values are identifiers, which is why those trailing spaces seriously get in my way.

This report is quite complicated enough without dialog manager's antics. I'm not even sure I'll be able to do it using WebFOCUS, it appears I'm running into the limits of what compound layouts can do.
