down one level in the present path (for the specified root- level command) 
of the command tree. You must separate command mnemonics from each 
other using a colon. You can omit the leading colon if the command is the 
first of a new program line.
Using a Semicolon (;)
Use a semicolon to separate two commands within the same command 
string. The semicolon does not change the present path specified. For 
example, the following two statements are equivalent. Note that in the first 
statement the first colon is optional but the third is compulsory.
:DISP:FORM DIG;:DISP:RES 2 
:DISP:FORM DIG;RES 2
Using a Comma (,)
If a command requires more than one parameter, you must separate 
adjacent parameters using a comma. 
Using Whitespace
You  must use whitespace characters, [tab], or [space] to separate a 
parameter from a command keyword. Whitespace characters are generally 
ignored  only in parameter lists. 
Using “?” Commands
The bus controller may send commands at any time, but a SCPI 
instrument may only send responses when specifically instructed to do so. 
Only query commands (commands that end with a “?”) instruct the 
instrument to send a response message. Queries return either measured 
values or internal instrument settings.
