[RPGNext] getTokens() bug...

[Joel Cochran <jrc@xxxxxxxxxx>]

Howdy Nexters,

I found a bug today in the getTokens() procedure: if the token character
is either the first or last (or both) character in the string,
"unpredictable results may occur".  I found it while tokenizing an IFS
path string:

myPath = '/my/test/path/' ;
getTokens( myPath : %addr( tokenArray ) : '/' );

The array returned a blank for element 1 and then only the first two
elements.  In the current version, the problem is masked by %trim()
operations if the token is blank (which is also the default).  While
correcting this, I also discovered that the %trim() operations were a
bug in their own right because they removed blanks, which may not be
desirable if the token is something other than blank, so I corrected
that as well.

The update is not currently available, so I'd like to judge from your
responses how quickly I need to get it out.  If it can wait until the
next general update, that's fine, but if there is anyone who needs it
I'll go ahead and do a small update.

Also, if you discover any kind of bug like this, please report it here
to the list.

Thanks!
