Example:
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 through 10) and n is the number of
digits to the right of the decimal point (0 through 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.
The variable format also affects returned values from internal variables such as _GNX.
PF and VF commands are global format commands. Parameters may also be formatted locally by using
the {Fn.m} or {$n.m} specification following the variable = . For example:
F specifies decimal 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. The local format is used with the MG* command.
