mview button help

I am trying to create a button that does the following:

Makes a layer named "viewport" with color 255, linetype continuous, set to Noplot.
Trigger the Mview command and pick my 2 corners of the rectangle.
Sets the current layer back to what it was at the beginning of the routine.

I have been able to do the layer manipulation with the following:

^C^C(setq exlay (getvar "clayer"));(command "layer" "m" "viewport" "c" "255" "" "l" "" "" "p" "n" "" "");(command "layer" "s" exlay "")

I have been placing the following mview line before the last layer command:

(command "mview" pause)

When I insert in the above, it works up to the point that I create the mview on layer viewport, but does not set the layer back to the original current layer.

Any help will be greatly appreciated.

Change it to (setvar "clayer" exlay)

 

Thanks, but I have tried this as well, but after I draw in the mview rectangle, I still remain on layer "viewport".

 

Here ya go... Note the 2 \\ They indicate a pause for user input, in this
case, the two corners of the mview.

^C^C(setq exlay (getvar "clayer"));(command "layer" "m" "viewport" "c" "255"
"" "l" "" "" "p" "n" "" "");mview;\\(command "layer" "s" exlay "");

 

Nice catch....Thanks.

 

Thanks a million!

You're welcome.

 

By the way, what does the ^m signify in your routine?
