(50G) TERMINAL VIEW (I/O) Printing and capturing data, emulating a terminal - compsystems - 12-19-2016 04:45 PM

Hello

I am emulating a terminal view.
FEATURES:
0: prettyPrint (math textbook)
1: font change (8/7/6/5) pixels
2: printing of GRAPHS (GROBS)
4: popups (choose, and menus) inside the view
5: input line

TO DO:
0: improve data capture on screen
1: horizontal scroll for large equations. (I think it is only feasible with system RPL) =( Who can help me?
2: print continuously (vertically) for now only a screen. (I think it is only feasible with system RPL) =(

Suggested, comments are welcome

files: Binary File (Library and test directory) VERSION 1.0.3
