You can determine the number of streams and use SELECT and all the other
stuff, but if you refer to a stream that isn't there, retribution will
be swift.
In short, you can do whatever you like.
addstream input or addstream output creates a single stream. I'm not
sure that was smart on my part.
In my opinion there is no need neither for an option nor a
configuration variable. Who has the hours to fine-adjust
processing with options may use a STRLIT IFEMPTY to achieve the
same. Fiddling with my OCT2>HEX rexx I found VERIFY does pass null
records too. So I use LOCATE to filter them out.
I flipped through The Book but did not find an example. When I
want an optional secondary stream in a REXX, do I have to query
for it and optional use '*..1:' or 'take 0' in my callpipe? Or is
there a canonical way to make the secondary connector act smart?
And, what do I have to do that
