	myScope.WriteString ":TIMebase:RANGe 0.5;POSition 0"
	The colon between TIMebase and RANGe is necessary because TIMebase:RANGe is a
N O T E
	compound command. The semicolon between the RANGe command and the POSition
	command is the required program message unit separator. The POSition command does not
	need TIMebase preceding it because the TIMebase:RANGe command sets the parser to the
	TIMebase node in the tree.
Example 2:	myScope.WriteString ":TIMebase:REFerence CENTer;POSition 0.00001"

Parser Back to	myScope.WriteString ":TIMebase:POSition 0.00001"
Root
	In the first line of example 2, the subsystem selector is implied for the POSition command in
N O T E
	the compound command. The POSition command must be in the same program message as
	the REFerence command because the program message terminator places the parser back
	at the root of the command tree.
	A second way to send these commands is by placing TIMebase: before the
	POSition command as shown in the second part of example 2. The space
	after POSition is required.
Example 3:	You can send multiple program commands and program queries for
Selecting	different subsystems on the same line by separating each command with a
Multiple	semicolon. The colon following the semicolon enables you to enter a new
Subsystems	subsystem. For example:
	<program mnemonic><data>;:<program mnemonic><data><terminator>
	For example:
	myScope.WriteString ":TIMebase:REFerence CENTer;:DISPlay:VECTors ON"
	The leading colon before DISPlay:VECTors ON tells the parser to go back to the root of the
N O T E
	command tree. The parser can then see the DISPlay:VECTors ON command. The space
	between REFerence and CENter is required; so is the space between VECTors and ON.
	Multiple commands may be any combination of compound and simple
	commands.
