' maximum) next to the channel number. It is not necessary, but

' can be useful for organizing the display.

myScope.WriteString ":CHANnel1:LABel ""CAL 1""" ' Label ch1 "CAL 1".

myScope.WriteString ":CHANnel2:LABel ""CAL2""" ' Label ch1 "CAL2".

Labels with more than 32 characters are truncated to 32 characters. Lower case characters
