Function
A
function performs an operation
that
may
or
may
not
display any results.
A
function may
not be
queried.
An
example
of
a function
is to write the
variable settings
to
flash memory
using
rfid:cfg.write
CR
.
Certain functions
that
display a value
or
series
of
values display
the
string between curly braces
for
easy parsing. For example,
the rfid:qid
function
output displays:
{0x00BB,
1,
0x0000
,80;0x00000080
1CD19
