A typical “prompt” command sequence follows the format below:
0@n,m,o,data
where
n
is the line number (1-4) you want the prompt displayed on
m
is the character position (1-20) where you want the
prompt displayed
o
is the character that determines whether the prompt is for
display only (0) or is waiting for data input (1) See the
table below for valid characters for this position.
data
is the data you want displayed
For example, the command
@1,1,1, Enter Quantity
would display
Enter
Quantity
starting at position 1 on line 1, then wait for the operator to enter
their data.
