6.2.4
Multiple Command Rules
The semicolon (;) can be used as a separator to execute multiple commands on a single line. The multiple
command rules are as follows.
Commands at the same level and in the same subsystem command group can be separated by a
semicolon (;) on a multiple command line.
For example:
CALCulate3:LIMit[1]:STATe <b>;STATe?
To restart commands from the highest level, a semicolon (;) must be used as the separator, and then a
leading colon (:), which shows that the restarted command is a command at the top of the command
tree, must follow.
For example:
:CALCulate[1]:FORMat?;:CALCulate[1]:KMATh:MMFactor <NRf>
The GPIB common commands can restart only after a semicolon on a multiple command line.
For example,
CALCulate3:LIMit[1]:STATe <b>;*IDN?
6.2.5
Command Path Rules
Each new program message must begin with the root command, unless it is optional (e.g., [:SENSe]).
If the root is optional, simply treat a command word on the next level as the root.
The colon at the beginning of a program message is optional and need not be used. Example:
:DISPlay:ENABle <b> = DISPlay:ENABle <b>
When the path pointer detects a colon(;), it moves down to the next command level.
When the path pointer detects a colon (:) after a semicolon (;), it resets back to the root level.
The path pointer can only move down. It cannot be moved up a level. Executing a command at a higher
level requires that you start over at the root command.
