Omitting Compound Command Headers ___________________________
When compound commands contain common initial parts (example:
:BEEPer:KEY
,
:BEEPer:JUDGment
), the common initial part (example:
:BEEPer:
) can be omitted just for subsequent commands.
The common initial part is known as the "current path," and until cleared, the cur-
rent paths of subsequent commands are determined to have been omitted when
analysis is performed.
The following shows an example of the procedure for using current paths.
Normal expression
:BEEPer:KEY ON;:BEEPer:JUDGment NG
Expression with current path omitted
:BEEPer:KEY ON;JUDGment NG
The current path is cleared when the power is turned on, the interface type is
changed, the device is cleared* (only for GP-IB), or upon detection of a colon (:)
at the beginning of a command or a message terminator.
Common command messages can be executed regardless of the current path.
Furthermore, the current path is not affected.
A colon does not need to be added to the beginning of simple and compound
command headers. However, Hioki recommends adding a colon to the begin-
ning of these headers to prevent them from being mixed up with headers that
have omissions and to prevent an incorrect operation from being performed.
* Device Initialization
This becomes the current path and can be omitted from subsequent com-
mands.
