The wording for BPCHAR (not to be confused with BPCHAR(N) is already<br>
&quot;blank-trimming&quot;, not &quot;blank-padded&quot;. And &quot;blank-padded&quot; is probably<br>
the least correct wording variant for BPCHAR, because this type has<br>
unlimited length and it&#39;s impossible to pad to the infinity.</blockquote><div><br></div><div>A given value has a finite length and there is just no restriction on what that length is.  All trailing spaces in the input are considered padding for purposes of comparison i.e., manually padding is added by the user as opposed to the system.</div><div><br></div><div>So bpchar(n) is automatically blank padded to a total length for a value of n characters.  bpchar also has padding blanks but they must be manually inserted during value creation.</div><div><br></div><div>I would leave the note of blank-padded for both and just point out the automatic vs manual distinction.</div><div><br></div><div>David J.</div><div><br></div>
