This will input a single character from the bar-code wand
and display it on the LCD screen.
Remarks This function acts exactly like INCHR, but with the
optional bar-code wand. The value is returned from the
bar-code exactly like a keyboard input.
VER.V09F
If a multiple character bar code is scanned then WINCHR
will return the first character and the rest of the code
will be ignored.
As with WINPUT
if any key is pressed prior to the bar code
input, then the input is taken from the keyboard instead.
NOTE: The bar code format must first be selected usi.ng the
WAND verb. The relevant wand firmware must be resident in
HIINTER as a system file. If
it is not, then a system file
error will result.
