Removing Leading Zeros from Response to Interrogation Commands
The leading zeros on data returned as a response to interrogation commands can be removed by the use
of the command, LZ.
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.
Formatting Variables and Array Elements
The Variable Format (VF) command is used to format variables and array elements. The VF
command is specified by:
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.
