Boolean parameters
Boolean parameters represent a single binary condition that is either true or false. 
For a false condition, the power supply will accept “OFF” or “0”. For a true 
condition, the power supply will accept “ON” or “1”. When you query a boolean 
setting, the power supply will always return “0” or “1”. The following command 
uses a boolean parameter:
Strings parameters
String parameters can contain virtually any set of ASCII characters. A string must 
begin and end with matching quotes; either with a single quote or with a double 
quote. You can include the quote delimiter as part of the string by typing it twice 
without any characters in between. The following command uses a string 
parameter:
DISP {OFF|ON}
DISP:TEXT <quoted string>
