Section 5: Remote commands
Return value
Several of the channel functions return a value for specified channels and channel patterns.
The return value for these functions is a string containing a list of comma-delimited return items. The
channelList argument of the ICL command determines the number and order of these returned
items.
When the channelList parameter for these functions is "slotX", the response first lists the
channels starting from lowest to highest. More specifically, the channels are returned in numeric
order.
When the channelList parameter for these functions is "allslots", the response starts with Slot
1 and increases to Slot 6 for the Model 707B. The Model 708B has only one slot, thus "allslots"
is the same as "slot1" for this model. Each slot is processed completely before going to the next.
Therefore, all Slot 1 channels are listed before Slot 2 channels.
When the response is numeric, but in string format, use the tonumber() function to convert the
string to a number. For example, sending these commands:
x = tonumber("1403")
print(x)
Results in:
1.403000000e+03
5-6
