Introduction

The two commands used to show and set values for the keywords that define the state of the instrument are show and modify. For short, you can use the commands s and m, respectively. Thus, the command typed into a window on lrisserver will display the current value for the keyword ttime, the total exposure integration time:
     s ttime
Similarly, the command
     m ttime=100
will modify the total exposure time to 100 seconds. These simple commands are actually aliases of:
     show -s hires ttime
modify -s hires ttime=100
For a complete list of all of the keywords that can be showed or modified, type s keywords. If you wish to find only keywords attached to a certain stage, say the comparison lamp system, pipe the command into the Unix command grep:
     s keywords | grep lamp

Examples

  1. Change the number of erase counts to 7:
         m erasecnt=7
  2. To change the frame number to 1000.
         m frameno=1000
