8.5.8 Abbreviating Messages with Compound Headers
This becomes the current path, and can be curtailed
from the following commands.
When several compound headers have a common head portion (for example,
:SYSTem:BEEPer and SYSTem:RESet etc.), then, when and only when writing
them directly following on from one another, this common portion (:SYSTem:
in this example) can be omitted.
This common portion is called "the current path", by analogy with the general
concept of the current directory in the directory structure of UNIX or MSDOS,
and until it is cleared the analysis of following commands is performed by
deeming them to be preceded by the current path which has been curtailed in
the interests of brevity. This manner of using the current path is shown in
the following examples:
Normal expression
:SYSTem:BEEPer_ON;:SYSTem:RESet
Abbreviated expression
:SYSTem: BEEPer_ON;RESet
The current path is cleared when the power is turned on, when a colon (:)
appears at the start of a command, and when delimiter is detected.
With the 3155, there are seven possible current paths:
:CONFigure:
:EQUipment:
:MEASure:
:MEMory:
:SYSTem:
:MEMory:READ:
:SYSTem:COMParator:
