^CE^SK0** READ FROM THE SCREEN - HP71 **
^CE^SK0---------------------------------
^SK1The following program segment enables a running BASIC program to display
with scrolling in either direction and moveable cursor on, to select from a menu
of options by placing the cursor against the selected option and then pressing
ENDLINE.
^SK1Use is made of the SCROLL keyword, found in the Text Editor (e.g. Translator
Pac.) I think that SCROLL is an important addition to the HP71 Basic commands,
because there is no other way that a long display line can be reviewed. (i.e.
scrolled back and forth) whilst a program is running.
^SK1I guess if the Lexfile for SCROLL can't be made available from the User
Library then it could be keyed in with the MAKELEX routine in the booklet 'HP-71
MADE EASY' by J. Horn.
