## Screen Dimensions
# Find current screen size
if [ -z "${COLUMNS}" ]; then
   COLUMNS=$(stty size)
   COLUMNS=${COLUMNS##* }
fi

# When using remote connections, such as a serial port, stty size returns 
0
if [ "${COLUMNS}" = "0" ]; then 
   COLUMNS=80
fi

## Measurements for positioning result messages
COL=$((${COLUMNS} - 8))
WCOL=$((${COL} - 2))

## Set Cursor Position Commands, used via $ECHO
SET_COL="\\033[${COL}G"      # at the $COL char
SET_WCOL="\\033[${WCOL}G"    # at the $WCOL char
CURS_UP="\\033[1A\\033[0G"   # Up one line, at the 0'th char
