The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Methinks there is a better way than what I am doing.
I have a string like "home/One/Two/sample.txt" and want to separate
it as two strings: "home/One/Two/" and "sample.txt". I will be doing
this in an SQLRPGLE program.
Suggestions on approach to this?
FWiW: If the %scanr() BIF is not available yet on your installed
release, and if the SCAN OpCode or %scan() BIFs are not desirable for
some reason, then if the ILE COBOL compiler is available, that language
has a REVERSE function for character string data. While there would be
more upfront processing, the reversed data probably would allow for the
code to look much cleaner than scanning forward through the data or
resorting to a [similarly clean but] by-character loop from the last
character.
From a past discussion thread with "Subject: SQL Reverse Function",
the referenced CBLLE example, IIRC, could be utilized [effectively:
reversed_string=reverse_string(original_string);] to reverse the string
to allow %scan() to perform as an effective %scanr():
