Field justifi cation:

R Right justifi cation.
C Center justifi cation.
N No justifi cation.
[-] A single leading minus sign in the prompt fi eld will cause the prompt to be
sent one time only after the form is retrieved (Keyboard Display Unit only).
[- -] A double leading minus sign in the prompt fi eld will cause the prompt to be
suppressed (Keyboard Display Unit only).
PROMPT An ASCII text fi eld that will be transmitted to the host or keyboard Display Unit
via the serial interface each time this command is executed. This prompt
requests the operator to enter the value for the variable.
Remarks
This command is used in forms that require unique data on each label. When
initializing variables, they must be defi ned in order (V00, V01, V02 etc.) immediately
after the FS command.
The fi eld justifi cation parameter affects the way the variable will be printed. When
left, right, or centre justifi cation are selected, the counter value will be printed left,
right or center justifi ed in an area with a width defi ned by the p
2
parameter. If the
number of digits in the counter value is less than the number of digits defi ned by p
2
,
the area will be padded with space characters.
If no justifi cation is selected, the fi eld will adjust to fi t the actual length of the data
and will not exceed the set maximum fi eld length, which may be useful when using
a counter as input data to a bar code.
To print the contents of a variable, the number of the variable must be included in the
"DATA" fi eld of the A (Print Text) or B (Print Bar Code) commands.
