This becomes the current path, and can be
curtailed from the following commands.
4.8 Abbreviation of Compound Commands
When several compound headers have a common head portion (for example,
:BEEPer:KEY and :BEEPer:COMParator, etc.), then, when and only when
writing them directly following on from one another, this common portion
(:BEEPer: 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 example:
Normal expression
:BEEPer:KEY ON;:BEEPer:COMParator NG
Abbreviated expression
:BEEPer: KEY ON;COMParator NG
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.
Messages with particular headers can be executed without relation to the
current path. Further, they have no effect upon the current path.
With the 3532-50/3522-50, there are 12 possible current paths:
:APPLication:DISPlay
:BEEPer:
:COMParator:FLIMit:
:COMParator:SLIMit:
:CORRection:
:LEVel:
:LIMiter:
:MEASure:
:RANGe:
:TRIGger:
:USER:
:SCALe:
