...and, lest anyone think that Ted's "crude method" would be too crude to be
useful, it is trivial to create a VB program that steps through the source,
screen-by-screen, while taking snapshots that it copies to notepad (or
straight to a PC file). Grabbing several thousand lines of source wouldn't
take
any more time than it would to page through several thousand lines of source
on the screen. Many TN3270 packages may even provide sample code with
the distribution.
Either you trust your programmer's ethics or you shouldn't provide access to
the treasured source. There is no in between.
