The reason is that the DMNAME variable is a string variable not a numeric value so Foxview smurfs. Ronald G.

We use it thru the environment which is logged in to control visibility. #Put this at the end of the /usr/fox/wp/data/init.user file # Variable for current dbar enviroment. gctsize=255 dmtlist=DBAR dmllist=ENV_VIS Then you must reboot the station for it to take effect. Now when you want something to be visible use the action in Foxboro to run a display command like the following. Setl $ENV_VIS$DMNAME 1 And when you want it to disappear use Setl $ENV_VIS$DMNAME 1 When you want appearance based on the environment login put the following in all the env files.(0 = 0FF AND 1 = ON) Dmcmd setl ENV_VIS$DMNAME 0 I used visibility with 2 states based on thresholds so I could eventually create combinations of visibility such as low/med/high detail or selected visibility based on logged in user. Such as 0 = off, 1 = operator, 2 = assistant operator, 3 = mine. Another little trick is I was able to create a display command to toggle the $OAJLOG on and off.(which is only visible in my environment) Ronald G.

Helps with clutter for operating conditions and then provides some detailed information when there is trouble.
