>Logically you can create an idiot form, set to fullscreen, activate and use it's KeyPress event, writing to the form. There are many ways to solve it like this.

barcode application acts like console one.
It asks barcodes , locations, lots, quantites etc and shows responces to them in screen.
Emulating this using forms requires huge re-write.
Can accept replaced with

?
cbarcode= space(20)
nrow = row()
@ nrow, 1 get  cbarcode
read
* Read places cursor to ent of screen, fix it
_screen.top= nrow*8
? 'enterd code', cBarcode
