Lua reserved words
You cannot use the following words for function or variable names.
and for or
break function
repeat
do if return
else in
then
elseif local true
end nil until
false not
while
In addition to the Lua reserved words, you also cannot use command group names as variable
names. Doing so will result in the loss of use of the command group. For example, if you send the
command digio = 5, you cannot access the digio.* ICL commands until you cycle the power to the
instrument. These groups include:
beeper gpib
bit lan
channel scan
digio slot
display status
eventlog timer
errorqueue trigger
format tsplink
