DINQUIRE Command 

The 

DINQUIRE

 command is used to get the information of the default value of a specific variable in the 

PJL Environment. (User Default Settings).   It is also possible to get the value for variables which PJL 
cannot change (Read-only).   

The returned value of User Default Settings is identical to the Control Panel Setting.

DINQUIRE

 command can request only one variable at a time.  If you would like to get information 

from more variables, send multiple 

DINQUIRE

 commands.
