There is a picture on the top half of the screen (LOAD IMAGE). On the lower half is varying text (generated wint PRINT). Is there a way to clear the lower half of the screen only, keeping the picture on the top half in place. I have OPTION LCDPANEL CONSOLE active.

I get it. You paste a box filled with background colour over the text.
Thx

Not sure what you are trying to do. If you want to constrain the console to work inside the box it can't be done. In a program you just use normal drawing commands as per the MM2/MM+/MMX manuals

Sorry but I have not use the BOX command yet. But if you use [lw] = 0:
BOX 0,MM.VRES\2,MM.HRES,MM.VRES,0,0,0
Does it draw a box without a border? If so can you use:
To clear the area and position the cursor to where you want it?

it looks like hkoetz is trying to create an adventure game, using one of the screen modes provided by the apple ][. as i recall, the apples had a split-screen mode where the top half was graphics, while the bottom half supported about a dozen lines of text. this text, when scrolling, did not affect the graphic image.
peter: does the MZ version of mmbasic support VT100 escape sequences? if it did, it would be easy to set up a text window smaller than the whole screen. does it support some sort of cursor positioning? i've never used mmbasic on an MZ processor myself.
if not already there, it would be useful if all versions of mmbasic that support redirecting the console to an attached LCD also supported VT100 escape sequences, or at least some subset thereof.
cheers, rob :-)

MZ MMBasic is the same as MM+ with respect to screen/console handling - no more, no less
