Eko I suggest that you look at running your two arrays off a ring menu. This will give you the on key facilities you need. You have to handle the array scrolling yourself by using DISPLAY program_array elements(n) to screen_array(m) statements and SCROLL screen_array UP/DOWN BY x statements all controlled from the ring menu which can have options for First, Last, Next, Previous, Screen switch and Tag plus hidden function key options, etc. One of the other advantages is that you can use highlights DISPLAY progarm_array elements(n) to screen_array(m) ATTRIBUTE(REVERSE) to indicate the currently selected array line and, if you want, all those lines that have been tagged, updated, etc using a different attribute. (Remember to reset on moving as well as highlighting on arrival) Hope this helps.
