| Don,
I had to laugh at your OTOH because when I started I had the same confusion over / and \. Being visual, I had to come up with a physical analogy. Unfortunately most analogies I could think of, like a gas gauge, were backwards. I found one that worked for me for /. It's silly but it worked.
I visualized the logic flow as a path with / as a ramp or switch and the variable as an obstacle. If the variable is empty or null the ramp flattens an the logic proceeds. If non null the logic has to backtrack around the obstacle.

Hello Steve,
My ambition was to “never have to read the Perl manual ever again”. So far it’s worked :-).
The killer combination for me is system admin facilities, combined with decent data structures and, above all, concurrency. I recently wrote a concurrent file system traverser (as part of a larger project to display my file system as a series of pie charts, so I could quickly see where all the space has gone). To my surprise, it was an order of magnitude quicker than du, despite the latter being written in C. It shows what using all the cores of your modern processor can do to performance.
OTOH, I wish I could remember which way round “\” and “/“ go: I have to look it up every time.

Hello Steve, If you are interesting what can be done with Unicon I can add a word from me. If I remember correctly I started to use Icon (from which Unicon is grown later) since ~1993. I have read by chance about Icon in some magazine (PC Magazine?) and it seemed to me superior thing. After world of Fortran, PL/1 and C it was like a shining diamond! So, I have written a letter to Ralph Griswold at Arizona University and he kindly sent me back the diskette with MS-DOS Icon (free of charge!). Step by step I struggled to learn Icon. It was very difficult without manuals (actually impossible!). But when I have got a printed book (gifted by American collegues) the process became fast. As Icon was suspened in progress after M-r Griswold have gone I started to search the alternatives. I knew about Unicon since beginning of 2000-s but still continued to use Icon. Nevertheless some years ago I completly migrated to Unicon. I have on sourceforge two projects: The first one is a kind of framework to perform any text transformation tasks. The second is a word analysis for text corpuses. Both are Windows applications and include GUI written on Lazarus (on Delphi early) and CLI written on Icon (Unicon). GUI communicates with CLI through Windows pipes. CLI can be builded with help of Icon or Unicon and can be ported to any OS which supports Icon/Unicon. One guy told that he successfully used xmarkup/wordtabulator GUI on Linux through Wine! Currently both these applications are used at http://rvb.ru site (Russian Virtual Library) for preparing of text publications. As for xmarkup I am currently preparing the new version of it. The wordtabulator is about frozen. The new version of xmarkup will unite the functionality of both projects. Hope, it would be interesting to probe it! Best regards, Sergey Didn't go through the first time.
Shawn, I've used Icon/Unicon in the past, but not so much recently. I am interested in what you and others use it for. I used it a few years ago to create a Windows app to keep track of families and men assigned to visit them. This was my first foray into Windows programming. It was a blast and many kudos to all the folks on this forum for their invaluable help! Steve

I am curious to hear from people how Unicon is working with Win 10. I've become kinda dependent on it, and my employer is getting ready to get everyone switched from Win 7, which I'm a tad nervous about. :( ------------------------------------------------------------------------------
