>Have you tried the inputbox() function? And why do you use so old commands instead of creating a form, where you can do whatever you want?

Barcode reader screen has approx 20 lines and 14 character per line.

I'm looking for a way to use console entry mode like

barcode 565465
quantity 66.444
barcode 4454655454
quantity 46.444
barcode 455565465
quantity 55.444
barcode 545565465
quantity 444.44

where previous enties are visible and are scrolling up on new entry.
accept command provides this natively.
inputbox() allows to enter only single value. After entry this value disappears from screen.
