Overiding Screen Output in a CL Program

Colin,

Just so long as this is just a general query and not something you may
actually try to do in CL, then the answer is 'Yes, you can do this'.

Check out the Virtual Terminal APIs section of the System API
Reference.  What you can do is start a virtual terminal session from
your CLP and then scrape the 5250 data streams returned from your
executed interactive (virtual) job.  This has all the drawbacks of any
screen scraper plus the wonderful learning opportunity for CL bit level
work; but could definitely be done.

I have done this type of thing in C and RPG; I personally would probably
lose patience rather quickly with CL but I have seen worse mappings of
using a particular language to write an application where the language
really wasn't oriented to the job at hand.
