Local Formatting of Response of Interrogation Commands
The response of interrogation commands may be formatted locally. To format locally, use the
command, {Fn.m} or {$n.m} on the same line as the interrogation command. The symbol F specifies
that the response should be returned in decimal format and $ specifies hexadecimal. n is the number of
digits to the left of the decimal, and m is the number of digits to the right of the decimal. For example:
Examples:
TP {F2.2} Tell Position in decimal format 2.2
-05.00, 05.00, 00.00, 07.00 Response from Interrogation Command
TP {$4.2} Tell Position in hexadecimal format 4.2
FFFB.00,$0005.00,$0000.00,$0007.00 Response from Interrogation Command
Formatting Variables and Array Elements
The Variable Format (VF) command is used to format variables and array elements. The VF
command is specified by:
VF m.n
where m is the number of digits to the left of the decimal point (0 thru 10) and n is the number of digits
to the right of the decimal point (0 thru 4).
A negative sign for m specifies hexadecimal format. The default format for VF is VF 10.4
Hex values are returned preceded by a $ and in 2's complement.
:V1=10 Assign V1
:V1= Return V1
0000000010.0000 Default format
:VF2.2 Change format
:V1= Return V1
10.00 New format
:VF-2.2 Specify hex format
:V1= Return V1
$0A.00 Hex value
:VF1 Change format
:V1= Return V1
